I should note that the recommended solution at the moment for "Win32 + CPAN" is the "CamelPack", which is a macro-installer that downloads and installs ActivePerl, nmake, and MinGW, then integrates them together properly.

in thread Installing CPAN modules without using 'ppm'
Please note that Win32 is still making the transition from PPM being the most common installation method to having CPAN installation as a viable option, and so your milage may vary a little.
Personally, I would recommend it only for experienced Perl people at the moment, as there are quite a few bugs in common modules that remain unresolved.
To download the CamelPack, and for all other Win32 information, see the http://win32.perl.org/ website.
