Thanks Martin, glad I stayed tuned.
I've never built anything from source, & i'm on windows (curses!), so a tar
ball is not something i have experiences with as such.
None the less, hopefully your reference will lead me to some useful
information. I'll explore my installation for examples & failing that, look
for some source code.
Thanks for checking the trash.

hermetic music * python * csound * possibly mindless ranting
various werk in perpetual delusions of progress....
