I normally run MacOS on my G3 (233MHz beige desktop), but your PPC build seems to work fine under LinuxPPC-1999Q3 (2.2.6-15 kernel) using the built-in audio (with "-frags 4 -fragsize 11" flags).
I'd also be interested in trying to get ALSA to work. Which version of the drivers sports the API most compatible with Pd in Intel-land?

I've put a linuxppc version of pd-032 up at http://mambo.peabody.jhu.edu/~karlmac/download for anyone who is interested. It is fairly well tested but not garuntees. Most likely you will have to specify -frags n to get it to work with the built-in sound. Hopefully I will get alsa to work on my G4 soon so that I can test full duplex (the only extra card I have is only full duplex with alsa). Is anyone else using linuxppc?
