This follow up of mine might be slightly off-topic for the module-build list, but as it still pertains to this thread, I'd rather avoid fragmen- ting it.

Now that Mail-SPF v2.005 has been released (with META.yml fixed to read
"version: v2.005" instead of "version: 2.005000"), I am still having
trouble with CPAN.pm:
| cpan[1]> r Mail::SPF
| CPAN: Storable loaded ok (v2.15)
| Going to read /home/julian/.cpan/Metadata
| Database was generated on Tue, 19 Jun 2007 21:08:40 GMT
|
| Package namespace installed latest in CPAN file
| Mail::SPF v2.005 2.005
JMEHNLE/mail-spf/Mail-SPF-v2.005.tar.gz
| 1 installed module has a version number of 0
How come CPAN.pm detects the "latest" version (on CPAN) as "2.005" rather
than "v2.005"? Doesn't CPAN.pm read the META.yml on CPAN to determine the
version number?
Julian.
