Strange. Obviously not what I get here (I get the help text as
requested). Things to check:

- did you install jack manually at some point? If so, make sure the jack
you are executing is the one from the rpm (/usr/bin/jackstart). It does
not look like it but there may be another jack around :-) "whereis
jackstart" should tell you where it is in your paths. 

- are the files there? two ways to check, first check the integrity of
the package with "rpm -V jack-audio-connection-kit", that should flag
files that are not there or have been changed. Another, just list the
files with "rpm -q -l jack-audio-connection-kit" and manually verify
they are there.
