So to summarize your and Winfried's messages, I can either get a newer
ALSA _OR_ upgrade to kernel 2.4.5.  I wonder what will happen if I do both...

As to the -alsa command line option being gone, try:
make clean
./configure --enable-alsa

(or --enable-old-alsa for 0.5x).

Pd uses only OSS midi; the "-alsa" flag affects only the audio code, not
the MIDI code.
