In case I get eaten by raptors (or someone else has to do this task in
the future), here's the gory details:

Nant is extremely sensitive about any changes made to its underlying
dependencies, specifically log4net, mono-nunit22, and mono-sharpcvslib.
Sometimes (possibly all the time), when these packages get rebuilt, or a
butterfly flaps its wings in Beijing, their symbols or locations in the
GAC change slightly, and nant will refuse to rebuild with the log error
you got above:

      [csc] The assembly was not found in the Global Assembly Cache, a
path listed in the MONO_PATH environment variable, or in the location of
the executing assembly

Here's how to fix it.

1. Set %{bootstrap} to 1 in nant.spec. Minor release increment in
nant.spec. Rebuild. {Tag package in buildroot}
2. Increment release in mono-nunit22.spec. Rebuild. {Tag package in
buildroot}
3. Increment release in log4net.spec. Rebuild. {Tag package in buildroot}
4. Increment release in mono-sharpcvslib.spec. Rebuild. {Tag package in
buildroot}
5. Reset %{bootstrap} to 0 in nant.spec. Major release increment in
nant.spec (drop minor). Rebuild (nant should now build cleanly).

This is easier to do with a chain build, but since chain builds only
work for unfrozen rawhide...I'm having to do this by hand.
