If you have no howl, then it’s not a fc3 based distro… might be rhel or fc2.
Two choices — either rebuild a source rpm (find on on dag or something and do:
rpmbuild –rebuild path/to/howl.src.rpm
that will build it, then install it
rpm -Uvh /usr/src/redhat/RPMS/i386/howl.rpm (or whatever the file name is)
—
Or, you can build the mt-daapd rpm with the fc2 specfile, which doesn’t use howl, it uses the built-in mdns responder.
