in reply to installing perl modules from cmd prompt in windows

Anytime I've installed modules on a Win32 system (not using PPM), I've done the following:

perl -MCPAN -e"install Blah::Blah"
or open a shell session via:
perl -MCPAN -eshell

Installing via CPAN on a Win32 system works great if you're using Strawberry Perl. You can get a copy from http://vanillaperl.com/. You can also read about it at the win32.perl.org wiki.
