rpm -ql jack-0.102.20-42.pm.1

/usr/bin/jack_bufsize
/usr/bin/jack_freewheel
/usr/bin/jack_load
/usr/bin/jack_unload
/usr/bin/jackd
/usr/lib/jack
/usr/lib/jack/inprocess.so
/usr/lib/jack/intime.so
/usr/lib/jack/jack_alsa.so
/usr/lib/jack/jack_dummy.so
/usr/lib/jack/jack_oss.so
/usr/lib/jack/jack_portaudio.so
/usr/lib/libjack.so.0
/usr/lib/libjack.so.0.0.23

yes, everything seems to work this way, package jackdmp has:

rpm -ql jackdmp-0.62-0.pm.1

/usr/bin/jackdmp
/usr/lib/jackmp
/usr/lib/jackmp/jack_alsa.so
/usr/lib/jackmp/jack_dummy.so
/usr/lib/libjackdmp.so
/usr/lib/libjackmp.so
/usr/share/doc/packages/jackdmp
/usr/share/doc/packages/jackdmp/ChangeLog
/usr/share/doc/packages/jackdmp/README


the scripts included:

postinstall scriptlet (using /bin/sh):
(
cd /usr/lib
[ -f libjack.so.0.0.23 ] && \
        /bin/mv -f libjack.so.0.0.23 tmp_libjack.so.0.0.23 && \
        echo "original jack saved as tmp_libjack.so.0.0.23" || :
/bin/rm -f libjack.so*
ln -s libjackdmp.so libjack.so.0
)
/sbin/ldconfig

postuninstall scriptlet (using /bin/sh):
(
cd /usr/lib
/bin/rm -f libjack.so*
[ -f tmp_libjack.so.0.0.23 ] && \
        /bin/mv -f tmp_libjack.so.0.0.23 libjack.so.0.0.23 && \
        ln -s libjack.so.0.0.23 libjack.so.0 && \
        ln -s libjack.so.0.0.23 libjack.so && \
        echo "original jack restored" || echo "jack not restored"
)
/sbin/ldconfig


so now we have:

/usr/lib # ls -l /usr/lib/libjack*
-rw-r--r-- 1 root root 320960 18. Feb 11:45 /usr/lib/libjackdmp.so
-rw-r--r-- 1 root root 217192 18. Feb 11:45 /usr/lib/libjackmp.so
lrwxrwxrwx 1 root root     13 20. Feb 08:28 /usr/lib/libjack.so.0 -> libjackdmp.so

Clients can connect /usr/lib/libjack.so.0 but starting ardour (i.e.) gives
the error above and exit.

by the way portaudio is available:
rpm -qa|grep  portaudio
portaudio-devel-19-114
portaudio18-18.1-0.pm.2
portaudio20-20.0-0.pm.2
portaudio-19-114
portaudio20-devel-20.0-0.pm.2
portaudio18-devel-18.1-0.pm.2

Do I understand it right: it's meant that clients can use /usr/lib/libjack.so.0
(symlink), and both jackd OR jackdmp should work as server that way?
Or is that symlink just to give clients connectivity to jackdmp?

Thank you for reading that all, but I want to have it solved.
