But when running athena I get: MacBook-Pro-de-Ricardo:~ rfaccio$ athena Can't locate Demeter/Here.pm in @INC (you may need to install the Demeter::Here module) (@INC contains: /Library/Perl/5.18/darwin-thread-multi-2level /Library/Perl/5.18 /Network/Library/Perl/5.18/darwin-thread-multi-2level /Network/Library/Perl/5.18 /Library/Perl/Updates/5.18.4 /System/Library/Perl/5.18/darwin-thread-multi-2level /System/Library/Perl/5.18 /System/Library/Perl/Extras/5.18/darwin-thread-multi-2level /System/Library/Perl/Extras/5.18 .) at /opt/local/bin/athena line 7.
