Thanks Adrian for the reply; and sorry.
It was in fact "jack-1.9.8"; and yes, I could build jack with --alsa support.

Here are the results ::


a)
After building jack with alsa support, I tested for jack server
running, as follows ::

Next, I re-tested portuadio now, as follows ::

Portaudio still can't get hold of the jack server; god knows why :-(

As expected, I am stick stuck on my original problem - the same
startup messages, and still cannot get "Import Audio" to work :-(
