If you want to check whether or not a particular module is available, you do that like this: 
eval 'require Win32::GetShortPathName';
if ($@) {
 # nope, not on this system
} else {
 # yes, go ahead with it
}

Note that you must leave out the "use" for the module.

Or were you asking how to tell what platform you're on?
