First of all, thank you Frank so much for making the MacPorts install possible for Demeter! I have installed it on my MacBook Pro running MacOS 10.8.5, and here is a short report in how well it is running. Hope this is of use. Athena opens and looks normal so far. I have no trouble loading data and plotting. Yay! I think feff and feffit also work, but I don't know how to use the command line version so I haven't been able to test them yet. Artemis fails (as we were warned) with segmentation fault that crashed Perl. Hephaestus also fails (as warned), in the same way. Atoms does not open, and the following errors are produced: Attribute (txx) does not pass the type constraint because: Validation failed fo 'Num' with value 1.0000000 at /opt/local/lib/perl5/vendor_perl/5.16.1/darwinthread-multi-2level/Moose/Exception.pm line 37 Moose::Exception::_build_trace('Moose::Exception::ValidationFailedForInineTypeConstraint=HASH(0x7fcb4fe83b40)') called at reader Moose::Exception::trae (defined at /opt/local/lib/perl5/vendor_perl/5.16.1/darwin-thread-multi-2leve/Moose/Exception.pm line 9) line 7 Moose::Exception::trace('Moose::Exception::ValidationFailedForInlineTypConstraint=HASH(0x7fcb4fe83b40)') called at /opt/local/lib/perl5/vendor_perl/5.6.1/darwin-thread-multi-2level/Moose/Exception.pm line 49 Moose::Exception::BUILD('Moose::Exception::ValidationFailedForInlineTypConstraint=HASH(0x7fcb4fe83b40)', 'HASH(0x7fcb4fe839f0)') called at /opt/local/ib/perl5/vendor_perl/5.16.1/darwin-thread-multi-2level/Class/MOP/Method.pm line128 Class::MOP::Method::execute('Moose::Meta::Method=HASH(0x7fcb4ff6fac8)','Moose::Exception::ValidationFailedForInlineTypeConstraint=HASH(0x7fcb4fe83b40), 'HASH(0x7fcb4fe839f0)') called at /opt/local/lib/perl5/vendor_perl/5.16.1/darin-thread-multi-2level/Moose/Object.pm line 56 Moose::Object::BUILDALL('Moose::Exception::ValidationFailedForInlineTypConstraint=HASH(0x7fcb4fe83b40)', 'HASH(0x7fcb4fe839f0)') called at /opt/local/ib/perl5/vendor_perl/5.16.1/darwin-thread-multi-2level/Moose/Meta/Class.pm line282 Moose::Meta::Class::new_object('Moose::Meta::Class=HASH(0x7fcb4fe873b0), 'HASH(0x7fcb4fe839f0)') called at /opt/local/lib/perl5/vendor_perl/5.16.1/darin-thread-multi-2level/Moose/Object.pm line 27 Moose::Object::new('Moose::Exception::ValidationFailedForInlineTypeConsraint', 'type_constraint_message', 'Validation failed for \'Num\' with value .0000000', 'class_name', 'Xray::Crystal::Cell', 'attribute_name', 'txx', 'value, ' 1.0000000') called at /opt/local/lib/perl5/vendor_perl/5.16.1/darwin-threa-multi-2level/Moose/Util.pm line 51 Moose::Util::throw_exception('ValidationFailedForInlineTypeConstraint','type_constraint_message', 'Validation failed for \'Num\' with value 1.000000', 'class_name', 'Xray::Crystal::Cell', 'attribute_name', 'txx', 'value', ' 1.000000') called at accessor Xray::Crystal::Cell::txx (defined at /opt/local/libperl5/site_perl/5.16.1/darwin-thread-multi-2level/Xray/Crystal/Cell.pm line 133 line 9 Xray::Crystal::Cell::txx('Xray::Crystal::Cell=HASH(0x7fcb4b01e998)', ' 1.0000000') called at /opt/local/lib/perl5/site_perl/5.16.1/darwin-thread-multi2level/Xray/Crystal/Cell.pm line 170 Xray::Crystal::Cell::geometry('Xray::Crystal::Cell=HASH(0x7fcb4b01e998)) called at /opt/local/lib/perl5/site_perl/5.16.1/darwin-thread-multi-2level/Xry/Crystal/Cell.pm line 73 Xray::Crystal::Cell::__ANON__('Xray::Crystal::Cell=HASH(0x7fcb4b01e998), 0, 0) called at accessor Xray::Crystal::Cell::b (defined at /opt/local/lib/pel5/site_perl/5.16.1/darwin-thread-multi-2level/Xray/Crystal/Cell.pm line 75) lie 15 Xray::Crystal::Cell::b('Xray::Crystal::Cell=HASH(0x7fcb4b01e998)', 0) clled at /opt/local/lib/perl5/site_perl/5.16.1/darwin-thread-multi-2level/Xray/Cystal/Cell.pm line 64 Xray::Crystal::Cell::__ANON__('Xray::Crystal::Cell=HASH(0x7fcb4b01e998), 0, 0) called at accessor Xray::Crystal::Cell::a (defined at /opt/local/lib/pel5/site_perl/5.16.1/darwin-thread-multi-2level/Xray/Crystal/Cell.pm line 69) lie 15 Xray::Crystal::Cell::a('Xray::Crystal::Cell=HASH(0x7fcb4b01e998)', 0) clled at /opt/local/lib/perl5/site_perl/5.16.1/darwin-thread-multi-2level/Xray/Cystal/Cell.pm line 144 Xray::Crystal::Cell::clear('Xray::Crystal::Cell=HASH(0x7fcb4b01e998)') alled at /opt/local/lib/perl5/site_perl/5.16.1/darwin-thread-multi-2level/Demetr/Atoms.pm line 302 Demeter::Atoms::clear('Demeter::Atoms=HASH(0x7fcb4b016358)') called at opt/local/lib/perl5/site_perl/5.16.1/darwin-thread-multi-2level/Demeter/Atoms.p line 316 Demeter::Atoms::read_inp('Demeter::Atoms=HASH(0x7fcb4b016358)') called t /opt/local/lib/perl5/site_perl/5.16.1/darwin-thread-multi-2level/Demeter/Atom.pm line 169 Demeter::Atoms::__ANON__('Demeter::Atoms=HASH(0x7fcb4b016358)', 'atoms.np') called at constructor Demeter::Atoms::new (defined at /opt/local/lib/perl5site_perl/5.16.1/darwin-thread-multi-2level/Demeter/Atoms.pm line 926) line 103 Demeter::Atoms::new('Demeter::Atoms', 'file', 'atoms.inp') called at /ot/local/bin/atoms line 72 Martha W.
