Perl allows _ in numbers to separate thousands.

    $ perl -E 'say 1_000'
    1000

(in fact, it can be used wherever one wants in a number:
    $ perl -E 'say 1_00'
    100
)

This is allowed also in versions, so cpan authors often use 1.20_01 or
1.200_001 to have something that looks like semver (x.y.z) but is still
parsed as a regular number. (yes, versioning sucks - I already wrote
about it here
http://jquelin.blogspot.fr/2009/05/rationalizing-perl-module-versions.html
and that's why we are sanitizing perl version numbers within mageia)

This patch only acknowledges this fact, and allows _ in versions.

hth,
