OK, i see the problem.

the postinstall script is just wrong: it should symlink libjack.so.0  
to libjackmp.so (NOT libjackdmp.so which is the *server*  shared lib  
used by the jackdmp and alsa, dummy backend)

Who did this rpm package?

Then the symlink is wrong here.

The rpm package has to be corrected
