Hmmm...yes, that's wrong, even though "1.0a" isn't technically allowed.
(I wonder if the Porters Handbook might need some revision.)

Well, geez, it's not like I *tried* to break the bloody damn thing. :-(
There are some pretty strange corner cases, and, I know you're aware of
this, the syntax of software package version numbers is not well
defined. When you start mixing letters and digits, it's exceptionally
messy.
pkg_version doesn't handle the 6.0aa > 6.0z case, and it'd be pretty
hard to make it do this without making a bunch of assumptions about the
semantics of the characters in the version numbers. You and I differ
on that point, I believe.

See patch attached.

I'd rather we try my patch, thanks. No offense, but my meager Perl
skills at least have a chance of understanding the code the way I
wrote it.
