I think the problem is with glibc-static.i686. Koji fetches
glibc32.x86_64 but this conflicts with glibc.i686 on my system.

More important I think grub doesn't like the gcc >= 4.6.0. As you can
see from https://bugzilla.redhat.com/show_bug.cgi?id=718722 there are
some mismatches between stage1/stage2 when they are recompiled with
gcc >= 4.6.0. Everything is fine with gcc=4.5.1 in fc14 though. You
can find some of the discussion on this here:
http://lists.fedoraproject.org/pipermail/devel/2011-July/153799.html .
I think this should have a higher priority than the deps because it
renders the bootloader and hence the whole system useless. I'm sure
those can wait till you're back.
