Problem about slashes and backslahes in library paths

[MathGon]

I installed Perl on Windows and I have problem to access Bioperl libraries.
My scripts are ok, I tried them on an other computer.

The error message is:

Can't locate Bio/PrimarySeq.pm in @INC (@INC contains H:/Perl64/site/lib/
H:Perl64/site.lib .) at H:\script.pl line 10

I tried to solve this problem by mining posts on forums but I didn't manage.

Have you an idea please?

Well, you've got a "mixed" pathname in @INC.  Anything that starts with  L:
would be a windows path while the use of forward slashes (/) is a Linux
path.  I'd suggest changing the script (or the environment which sets @INC)
so it uses only Windows or Linux paths.

There may be some Perl scripts that one is supposed to run to setup the @INC
variable correctly for ones current system (presumably depends on the
supplier of Perl for your Windows installation).

Or you could switch to Linux which I would consider to be a much more
Perl/BioPerl friendly environment.  Because, IMO, sticking with Windows is
like boarding the Titanic as it is about to sail out of the harbor.

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).
