Or maybe it came from using mingw with a Perl built with MS's compiler

Yes, that appears to be the trouble - though, assuming that the op is using a recent build of ActivePerl (which appears to be the case), there should be no such problem when using MinGW.

The specific problem I notice in the output provided by the op is that "-out:" is a VC++ flag. The comparable flag for MinGW is "-o". When MinGW sees -out:some_file, instead of trying to write to some_file, it tries to write to ut:some_file which, of course, is not a valid path.

I don't know why it is that the op is getting that VC++ flag. It looks like the fact that MinGW is in use is being overlooked somewhere along the way - possibly in ExtUtils::MM_Win32.

It may help us if we could see the output of perl -V (that's an upper case "V"), and if we also knew the version of ExtUtils::MakeMaker that's installed on that perl. (For the latter, run perl -MExtUtils::MakeMaker -e "print $ExtUtils::MakeMaker::VERSION")

Cheers,
Rob
