Hi, let's see what we can do: 1) If I test the new script by Bruce I get the following message: stefano% perl Makefile.PL === The Ifeffit wrapper, Athena, Artemis, and Hephaestus === This is Mac OSX. Checking dependencies ... Dependencies ok. Cool! Reading configuration file: Ifeffit/lib/athena/athena.config Reading configuration file: Ifeffit/lib/artemis/artemis.config Assembled athena.pl from its parts (athena_parts/). Assembled artemis.pl from its parts (artemis_parts/). Assembled hephaestus.pl from its parts (hephaestus_parts/). Fixing execution path in the Athena, Artemis, and Hephaestus executables... Changing athena.pl to /usr/bin/perl Changing artemis.pl to /usr/bin/perl Changing hephaestus.pl to /usr/bin/perl Changing ifeffit_shell.pl to /usr/bin/perl Changing rdaj.pl to /usr/bin/perl Changing atoms.pl to /usr/bin/perl Checking if your kit is complete... Looks good Checking if your kit is complete... Looks good Writing Makefile for Archive::Zip ERROR from evaluation of /Applications/Ifeffit/bin/horae-061/0CPAN/Makefile.PL: ERROR from evaluation of /Applications/Ifeffit/bin/horae-061/0CPAN/Archive-Zip-1 .16/Makefile.PL: Unable to open MakeMaker.tmp: Permission denied at /System/Libr ary/Perl/5.8.6/ExtUtils/MakeMaker.pm line 869. # Looks like your test died before it could output anything. 2) If I just type 'ifeffit' from the command line I get the following: stefano% ifeffit dyld: Library not loaded: /usr/local/lib/libpgplot.dylib Referenced from: /Applications/Ifeffit/bin/ifeffit Reason: image not found Trace/BPT trap 3) If, after I reinstalled everyhting from the ifeffit-1.2.8-Mac10.4.1.pkg.dmg, I launch feff from Artemis, using one of the tutorials on copper, I get the following message: Running feff (this could take a few minutes, please be patient) ... Uh oh! That Feff calculation did not run successfully. It seems to me that not only the problem arises when an upgrade is available, but, at this stage, also with the ifeffit-1.2.8-Mac10.4.1.pkg.dmg installer...
