Cute.

I looked for that just now with 'locate ladspa' and found no
such symbolic link. But, I did find /etc/profile.d/ladspa.csh
and /etc/profile.d/ladspa.sh, each of which set LADSPA_PATH in
the environment. I had my LADSPA_PATH set to /usr/lib/ladspa/
and I don't set that in my shell's RC files anywhere. I unset
LADSPA_PATH in my environment and found that now audacity finds
only one copy of each plugin.

With LADSPA_PATH set, then listplugins finds one copy of each
plugin. With LADSPA_PATH unset, then listplugins complains about
that and finds zero plugins.

I haven't looked with jack-rack.

Yes, I've seen that as well.

I don't know that unsetting LADSPA_PATH could be considered a
fix. But, it does seem to reduce the annoyance. I say it's not
a fix because I would think a fix would show the right number
of plugins in applications like audacity and with ladspa's own
listplugins.

Interesting.....
