Hi Dan,

thank you very much for your help and effort in examine this beast
(oh, I like it, if words have more ways to understand them, hihihi!)

What about installing libpng 1.2 manually in /usr/local (not using 
portage but good ole make/gcc).
I think, /usr/local is made for this kind of stuff and it should
not interfere with the rest of the gentoo world.
And it can easily be fixed if it does interfere nevertheless.
If libpng is the only thing...

I will try that...but...one question:
What do I need to patch/modifiy/crank in the configuration script
of the beast to point it to /usr/local?

Another interesting programs of this kind are:
puredata (aka pd)
chuck
csound

Have a nice weekend!
Best regards,
Meino
