Hello, When I attempt to open Artemis on OSX Yosemite (10.10.2) the error message copied below prints to the terminal. The initial image that indicates Artemis is opening does appear, although Artemis fails to open. Athena and Hephaestus open without error. Any suggestions as to how this could be resolved would be appreciated. Thanks, George $ artemis Can't locate Math/Round.pm in @INC (@INC contains: /opt/local/lib/perl5/site_perl/5.16.3/darwin-thread-multi-2level /opt/local/lib/perl5/site_perl/5.16.3 /opt/local/lib/perl5/vendor_perl/5.16.3/darwin-thread-multi-2level /opt/local/lib/perl5/vendor_perl/5.16.3 /opt/local/lib/perl5/5.16.3/darwin-thread-multi-2level /opt/local/lib/perl5/5.16.3 /opt/local/lib/perl5/site_perl /opt/local/lib/perl5/vendor_perl .) at /opt/local/lib/perl5/site_perl/5.16.3/darwin-thread-multi-2level/Demeter/ScatteringPath.pm line 44.
