How is one supposed to use RT Audio?  I have the system build with
PortAudio but I get

cage:~/Sourceforge/csound5> ./csound examples/trapped.csd -o dac:plughw:0
Localisation of messages is disabled, using default language.
Error '/usr/lib64/libportaudio.so: undefined symbol: jack_frame_time' in dlopen(./librtpa.so).
WARNING: could not open library 'librtpa.so'
ALSA real-time audio module for Csound by Istvan Varga
PortMIDI real time MIDI plugin for Csound

Why is it going on about ALSA when i did not ask for it?  I do not use
Jack and have not built with that either.

I take it back; CS5 no longer works as it once did

Off to teach, so no more on this today

/usr/lib64/libportaudio.so depends on the JACK library, as clearly stated
by the above messages. So, you either need to install the JACK library
and build with useJack=1 (which was the default last time I checked), or
rebuild PortAudio from sources without JACK support.

While ALSA was compiled, it is only used if you request it by using this
option:
   -+rtaudio=alsa
Any number of modules can be built, however, the default is always
PortAudio. The message about ALSA only means that the ALSA plugin was
loaded, and not that it will be used instead of PortAudio.
