Thanks for your help on this point (as well as the others who have pointed 
out the same thing), but I can't even rebuild the binary RPMs on a Red Hat 
system without removing the following lines from the spec file:

  BuildRequires:         alsa-lib-devel >= 0.9.0
(and, in the %files section:)
  %{_libdir}/ao/*/libalsa09.so

The actual libasound.so.2 dependency is automatically introduced by the 
RPM build process, and can be disabled, as described by Bill Nottingham 
earlier.

I don't see much value in creating RPMs that can't even be rebuilt on the 
intended target system, so I don't see how I can create redhat-friendly 
RPMS (and SRPMS) of libao without disabling alsa support.  I understand 
the desire to retain alsa support so the same RPM can be used on different 
distributions, I just want better behaved RPMs more :)

On a related note,
I understand that using --force with the vorbis.com RPMs will work, and 
I'll make a note of that on my web page.  But I still think that 
publishing RPMs that are claimed to be "for RedHat Linux", that do not 
install gracefully or rebuild on Red Hat machines, may frustrate potential 
users.

If --force or installation of other third-party RPMs is _intended_, it 
should be documented on the download page.
