I'm starting a new topic for this as it is a separate issue...
Running csound5.07 on Ubuntu 7.10.

I am able to render sound files to HDD and then play in an external media 
player, but am unable to render and listen in real time.

There error received is: *** error: unknown rtaudio module: 'PortAudio'
I have also tried running csound with +-rtaudio=alsa, that is 

$ csound -odac -+rtaudio=alsa  endless.orc endless.sco

and similarly receive  *** error: unknown rtaudio module: 'alsa'.

Have the following packages installed:
libportaudio0 - v18
libportaudio2 - v19
libportaudiocpp0

Have also tried running csound with just libportaudio0 installed, or just 
libportaudio2 installed, same problem.

ALSA packages installed:
alsa-base
alsa-utils
libasound2
libesd-alsa0
libsdl1.2debian-alsa
linux-sound-base

code of problem:

Anyone help with fixing this problem?  There was another thread similar but 
the resolution wasn't clear...
