That was exactly it for the record.
#which text2wave
#                         <-- before apt-get install festival
#which text2wave
/usr/bin/text2wave
# echo 'This is an example of using tts_commandline' | text2wave -f
8000 > test.wav
# file test.wav
test.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16
bit, mono 8000 Hz
# ls -l test.wav
-rw-r--r-- 1 root root 60208 Mar  4 06:44 test.wav
And the freeswitch debug log that shows it works:

Thanks for the help.
The reason I tried to start with tts_commandine is I have been
struggling for a couple of weeks to get MRCP to produce something
useful so I thought I would try something simpler and I could swear
mod_tts_commandline was listed as a requirement. But it could have
been on something else as I have been pouring through every document I
can find to figure this out and I probably got confused.
Thanks again!
