These are entirely unrelated modules which just happen to contain Win32 in 
their name.

This is the Win32 module.

/lib/perl5/site_perl/5.8.2/

Interesting. My FC2 linux boxes include all paths back to 5.8.0
My SuSE 9.1 box only includes a single versioned path.

I don't know enough about perl internals to say why this is.

Win32 is a seperate package (perl-libwin32).

It's essentially a lack of planning/coordination between the perl and 
perl-libwin32 maintainers.
