I'm confused as to the ver num, it seems to be 3.50 and 4.55 ???

$VERSION = '4.55';
3.50 is his CVS version, which is completely irrelevant in this case. There is no reason why the author should make a release every time he makes a minor change in his code - indeed in most cases, he will make many changes and many CVS commits between releases.
The automated tools most developers use to make CPAN releases quite correctly ignore the CVS version, and only take into account the $VERSION setting.
Therefore 4.55 is the correct version.
