This looks like a mismatch of the way how CPAN.pm and version.pm
handle the stringification of the numification of version objects.
When CPAN.pm calculates the number, it never has trailing zeroes, when
version.pm calculates the number, it often appends trailing zeroes.
There's not much you can do about it. Some day CPAN.pm will switch to
using version.pm directly and hopefully this will then resolve your
issue. But I'm not yet up to it.

I fear it won't. Switching to pure numeric versions would help and
switching to versions with two dots but without trailing zeroes would
also help (I think). But John Peacock certainly knows better than me
which solutions else should work reliably.
