Win32API under Cygwin not installing
Well first look at this and I would say did you try and installed using the -force option? That will install the module and ignore the failed tests. In many cases this will work.
I have seen this error a lot and forced the install and the module has worked fine.
I am confused? You put Cygwin on your box just to do Perl developement. If that is true is there a reason that you just didn't install Activestate Perl for Win32. Its very slick and the module updates flow like butter at a chik-fil-a store.
Is there is some other reason you are using Cygwin?
