Paul's thing worked perfectly. JACK-RACK apparently considers LADSPA_PATH to be a complete path and uses it exclusively. So I was able to move just the couple things I need for my live work over to a directory, and set my scripts to set LADSPA_PATH to just that directory before starting jack-rack. Since it's all in a script, my shell's LADSPA_PATH isn't mangled, and everything else still works fine. Cuts about 3 minutes off of the time it takes to set up for a gig; always a helpful thing.
