[LAU] Sineshaper. GUI refuses to open

I built Sineshaper 0.4.2 from the tarball. No problems with the build, and running it as, jack-dssi-host -v sineshaper.so results in an audio connection in qjackctl, and the midi connection is there, so that I can connect my midi keyboard, but no GUI for Sineshaper is opening. See output below. djmons@debian:~$ jack-dssi-host -v sineshaper.so jack-dssi-host: Warning: DSSI path not set jack-dssi-host: Defaulting to "/usr/local/lib/dssi:/usr/lib/dssi:/home/djmons/.dssi" jack-dssi-host: Looking for library "sineshaper.so" in /usr/local/lib/dssi... found jack-dssi-host: instance 0 on channel 0, plugin 0 is "sineshaper/ll-sineshaper/chan00" jack-dssi-host: registering osc.udp://debian:14911/dssi jack-dssi-host: sineshaper/ll-sineshaper/chan00 program 8 is MIDI bank 0 program 8, named 'Nasty' jack-dssi-host: sineshaper/ll-sineshaper/chan00 program 7 is MIDI bank 0 program 7, named 'Cosineshaper' jack-dssi-host: sineshaper/ll-sineshaper/chan00 program 6 is MIDI bank 0 program 6, named 'Noisy' jack-dssi-host: sineshaper/ll-sineshaper/chan00 program 5 is MIDI bank 0 program 5, named 'Clean' jack-dssi-host: sineshaper/ll-sineshaper/chan00 program 4 is MIDI bank 0 program 4, named 'Soft' jack-dssi-host: sineshaper/ll-sineshaper/chan00 program 3 is MIDI bank 0 program 3, named 'Bright' jack-dssi-host: sineshaper/ll-sineshaper/chan00 program 2 is MIDI bank 0 program 2, named 'Woodpecker' jack-dssi-host: sineshaper/ll-sineshaper/chan00 program 1 is MIDI bank 0 program 1, named 'Tremolo pad' jack-dssi-host: sineshaper/ll-sineshaper/chan00 program 0 is MIDI bank 0 program 0, named 'Default' jack-dssi-host: OSC URL is: osc.udp://debian:14911/dssi/sineshaper/ll-sineshaper/chan00 checking sineshaper_gtk against ll-sineshaper checking sineshaper_gtk against sineshaper jack-dssi-host: trying to execute GUI at "/usr/local/lib/dssi/sineshaper/sineshaper_gtk" host: Ready This is on a Debian Etch install, with KDE. I installed libglademm, and gtkmm, which were necessary to compile Sineshaper, and since then I've been installing all the glade, and gtk stuff I can find in synaptic, but cannot get Sineshapers GUI to open. Any suggestions as to what I'm missing? Thanks for any help Nigel.
