It's possible - likely even - that ActiveState has not created a PPM package for it. There are other package repositories; see http://win32.perl.org/wiki/index.php?title=PPM_Repositories for a good list.

If none of the repositories has a package, you can download the tarball from CPAN. It's a pure Perl module, so you don't need a compiler. The standard

> perl Makefile.PL
> nmake
> nmake test
> nmake install
[download]

should work fine.
