Also, that last directory is a bit odd: H:Perl64/site.lib
Regardless, the message means the perl executable used from command
line or called from the shebang line can't find BioPerl in @INC.
Another way to check is using 'perldoc -l Bio::Root::Root'; replace
Bio::Root::Root with any BioPerl module. You can set PERL5LIB to
point at your local BioPerl directory, but for Windows you really
should install it. It should work using PPM or CPAN with ActivePerl
and CPAN with Strawberry Perl.

Ah, let's not start that up here, please? The more users we have the
better. I much prefer to use Ubuntu 9.10 and OS X, but some of the
devs (me included) have put a decent amount of work trying to get
things working on WinXP (to the point of having a local VM).
