Description of problem:
cpanspec is broken when being used with perl-5.10 (fc9)

# cpanspec --packager foo -o -s Test
Module::CoreList does not support perl version 5.010000!
Version-Release number of selected component (if applicable):


How reproducible:
Always.

Steps to Reproduce:
1. cf. above

Expected results:
function.

Additional info:
AFAIS, the culprit is http://rt.cpan.org/Public/Bug/Display.html?id=32047
i.e. Module::CoreList's silly versioning.

This breaks cpanspec's "$Module::CoreList::version{$]}" because
in cpanspec $] expands to 5.010000 (trailing zeros),
while the keys in CoreList are floats (They expect 5.01).

Cf. /usr/bin/corelist -v 's output:
$ corelist -v
...
5.01
...

Though I think, the actual bug to be in Module::CoreList, this hack below would
get cpanspec going again:
