Perhaps I can provide some detailed info of the current state of the
build environment.
Note that I did 'updatedb' to get fresh 'locate' results.

It seems that speex is indeed statically linked but still missing (at
least) one speex symbol:

We must be sure of which versions of speex and portaudio we are using
to avoid the "dll hell".
This is not so strange since it is exactly how it worked with the old
iaxclient build system
where speex and portaudio were compiled together with iaxclient code.
