I deinstalled XML::LibXML::Common - and during reinstall, I tried to provoke an installation error (by messing around with temporary files on which Perl/lib/ActiveState/ModInfo.pm::parse_version()" is called (which produces your error). In the end, I *didn't* manage to prevent XML::LibXML::Common from installing ;-)

So there has to be some other crazy stuff in the way ...
