I guess Justin this is the dependency problem you mentioned?

The issue, and the reason why we have it in the F15 package, is so
that you can't mix libguestfs built against glibc >= 2.13.90-4 with
runtime glibc < 2.13.90-4.

Since glibc won't be updated to 2.13.90 in Fedora 14 (I hope), for
virt-preview you can just drop this extra dependency or add an
%if ... %end around it.

Requires:      glibc >= 2.13.90-4

This implies that even if I build it with glibc-2.13.0, it still won't work.

Maybe the comment is badly worded, but the problem is not that you
can't build against particular glibc.  It is that if you build with
glibc < 2.13.90-4 then you must install with glibc < 2.13.90-4, and
conversely if you build with glibc >= 2.13.90-4 then you must install
with glibc >= 2.13.90-4.  There is no way to express this using RPM
dependencies.
