conflicting i86 and x86_64 in repo?

[tomhorsley at adelphia.net]

Last night I was updating my FC6t1 system that is an x86_64 box. I installed this
from the DVD iso and have always gotten updates since then by running pup.

I got conflicts last night that were complaining about some library being
needed by gnopernicus, so I did an rpm -q gnopernicus and found I had
two gnopernicus rpms installed, both the same version, one i386 and one
x86_64. Usiing the --list option, I found both of them install many files
with the exact same name (no /lib versus /lib64), so it is hard to see how
both rpms could actually be correctly installed simultaneously.

Has pup screwed up at some point and installed i386 rpms when it should
have picked x86_64 ones? Have the repos gotten corrupted at some point?
Or is it really legitimate to have two conflicting rpms like this?
