<sigh> rpm 4.0.4 had a non deterministic version sort for numbers versus
letters

so you're looking for the newer package
and you're comparing 0 vs a

in rpm > 4.1.1 it's deterministic - numbers are always newer than
letters.

in rpm < 4.1.1 it's not fun.

a > 0
0 > a

depending on which one you sort first - ie:

if I ask
vercmp(a, 0)
it tells me a is newer
vercmp(0, a)
it tells me 0 is newer

see the problem?
