Hi Dave,
Let's keep the discussion on the mailing list so we can make sure that
when this problem is solved, its resolution will be archived.
I don't really understand what is going on either, though it would
probably be a good idea to set your PERL5LIB env variable so that when
you execute this script from the git repository that it will also uses
BioPerl modules in the git repository instead of the ones that are
installed in your "normal" path.
Also, are you using any command line flags when executing it? I didn't.
Scott
