Quite a difference in what? Or compared to what?

I tried emerge -vC the core Parse-CPAN-Meta and the Virtual
Parse-CPAN-Meta
Then eix-sync, then emerge -vuD world
When it gets to building `perl-core/Module-Build-0.400.0'
The same failure happens:

emerge has installed two very different [...]//Parse/CPAN/Meta.pm

And they say very different things:

$Parse::CPAN::Meta::VERSION = '1.4404';

One looks for 1.40, the other for 1.4404
I don't know what the code does but, is this possibly the problem? If
so its not at all clear what to do about it.
qfile on /usr/lib/perl5/5.12.4/Parse/CPAN/Meta.pm
Shows it comes from the main perl installation:
qfile /usr/lib/perl5/5.12.4/Parse/CPAN/Meta.pm

| dev-lang/perl (/usr/lib/perl5/5.12.4/Parse/CPAN/Meta.pm)

So that is from the main perl installation.
Just renaming /usr/lib/perl5/5.12.4/Parse/CPAN/Meta.pm to
/usr/lib/perl5/5.12.4/Parse/CPAN/XMeta.pmX
Causes a new miss match on version when building
perl-core/Module-Build-0.400.0
,----

So it appears there is some deeper mangling somewhere.
