I think that Win32::Process is included in Activestate Perl 5.8, although I'm not sure. Try this:
perl -MWin32::Process -e 1

If you don't get any errors, you're good to go. This error 
'cl' is not recognized as an internal or external command,
operable program or batch file.

means that you don't have a C compiler installed. When you install modules that have ".xs" components, you need a C compiler. Specifically, you need to use the same C compiler that was used to compile the particular 'perl' program you are using, in this case Microsoft Visual C++. The good news is that you can use the Standard or even, I think, the Learning Edition to compile XS modules. It's not too expensive.
