Apart from the t/pod.t failure (which is the only failure you're getting), I get the same output on Cygwin (and native Win32).

That t/pod.t failure is a rather strange one. Try building the module inside the Cygwin installation (eg in a specially created ~/perl_build directory), or at least in a directory whose name doesn't contain any white space.

If all else fails, I'd just install the module anyway. The t/pod.t tests are simply testing that the pod documentation renders ok. It's unlikely that there's anything wrong with the pod, but even if there is, the module will still be perfectly functional. (You would just have trouble reading the documentation.)

If you're really bothered by this, and don't get a satisfactory explanation here, try the cygwin mailing list. Other than that, you could perhaps try an earlier version of Parse::RecDescent.

Cheers,
