You are probably missing the alsa-lib-devel package, just install it:
  apt-get install alsa-lib-devel

The Jack build for FC1 undoes the prelinking off jackd on startup. It is
a gross hack but works well. Make sure that the Jack package you have
installed in the FC1 machine is the one for FC1...

The other thing that could be happening is that you do not have the
prelink package installed, so jack cannot find the binary. If so let me
know because then I'm missing a requirement in the jack spec file. Do an
"apt-get prelink" to install it if missing.
