That's a rather convoluted issue. Can you be more specific what you're trying to do? Here are some qualifying questions (not mutually exclusive): * What version.pm "thinks" -- meaning internal representation? * What version.pm will output as a string? What it will output in 'normalized' form? In numeric form? (All of these can differ) * What version.pm will make of the EU::MM->parse_version result? E.g. "say version->new( ExtUtils::MM->parse_version($file) )->normal" (Also, depending on the version of EU::MM, it will load version.pm if available) * What Foo->VERSION will give if version.pm is loaded? (Not necessarily the same as the parse_version result) * Which version of perl? 5.6.X? 5.8.0? 5.8.[1-9]? 5.10.X? All potentially different answers Given all that, I know of nothing on CPAN that can easily (and correctly) answer your question. Aren't you glad you asked? :-) -- David
