Subject: In Gentoo, 1.0 is greater than 1
X-Git-Tag: v0.12~14
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FCPANPLUS-Dist-Gentoo.git;a=commitdiff_plain;h=7bee20385150f2ebb608178ecdce3851cdc4f54f

In Gentoo, 1.0 is greater than 1

See also http://dev.gentoo.org/~ulm/pms/4/pms.html#x1-28008r2 for a complete
Gentoo version comparison algorithm.

Thanks Torsten Veller for bringing this to my attention.
