Do you have more than one version of jack installed, eg. one
in /usr/lib and one in /usr/local/lib? You might have seen
this already, but it's important:
http://subversion.ffado.org/wiki/AvoidingParallelInstallations.

If the documentation at ffado.org doesn't help you solve the
problem, the jack-devel mailing list might be a better place
to ask.
