Looks like you're missing the sine oscillator plugin I used in that 
patch.  (My example patches are a bit crap right now I have to admit, 
apologies for that).

I can't remember which sine oscillator I used - I would highly 
recommend just going out and getting every single LADSPA plugin you can 
get your hands on.

That error message is a little less than informative - when I get back 
home (I'm travelling w/o a laptop right now), I'll flesh it out to be a 
bit more descriptive and give you some information about that plugin 
that's missing.

Also, in the next version (currently slightly broken in CVS, but will 
be out early August) has DSSI (and LADSPA and Alsa etc) as an optional 
build dependancy so you'll be able to build without it.

As for maintained and stable, I usually try to be very present and on 
top of people's problems when they're brought up.  Keep in mind for 
things to get better I need feedback - never hesitate to bring up 
things you would like to see happen!
