It makes a difference right now only where the absolute module doesn't 
have a version (because in Build.PL we ask for at least version 0, which 
fails if version in the modules is actually undef). I'll fix that in the 
future, so it is best to use the absolute module for clarity.

In what way is it testy? I set up a new WinXP machine today and 
installed ActiveState. My Build.PL script happily offered to install 
Module::Build for me with CPAN and it almost worked up until CPAN needed 
nmake. After installing nmake I upgraded CPAN with no problems and then 
everything worked after that (I only tried to install one optional dep 
with Build.PL via CPAN, and that worked fine).

So yes, I'd say it holds true for Windows. Though I haven't sorted out 
the ppd stuff yet.
