[PD] dssi-vst.so possible?

[patrick]

hi,

i am trying to use VST under linux / pd.

i have no problem using jack-dssi-host:
http://probing.wikidot.com/using-vst-on-linux-with-jack

for pd, i compiled externals/postlude/dssi. the example is working 
perfectly (hexter.so, sine). next i am trying to use dssi~ like this

[dssi show]
|
[dssi~ dssi-vst.so:FreeverbToo.dll]

========================================
dssi~: DSSI/LADSPA host - version 0.95
========================================

dssi~: can't open dssi-vst, unable to find GUI
dssi~: 1 instances of FreeverbToo.dll, ready.

banging [dssi show]
dssi~: can't open dssi-vst, unable to find GUI

how can i show the GUI of FreeverbToo.dll and not dssi-vst?
