[orca-list] Building Orca and BRLTTY/Liblouis

["Rob" <captinlogic gmail com>]

I just pulled Orca:
https://github.com/GNOME/orca.git
and ran:
PYTHON=/usr/bin/python3 ./autogen.sh
./configure -q --prefix=/usr \
--sysconfdir=/etc \
--localstatedir=/var
At the end, configure whined:
./configure: line 3121: YELP_HELP_INIT: command not found
(that's expected; I don't have many documentation packages)
config.status: WARNING:  'src/orca/orca_i18n.py.in' seems to ignore the --datarootdir setting
config.status: WARNING:  'src/orca/orca_platform.py.in' seems to ignore the --datarootdir setting
NOTE: Braille support requires BrlTTY >= 3.9 and BrlAPI >= 0.5.1.

Use speech-dispatcher: yes
Use brltty: no
Use liblouis: no
Use gstreamer: yes
The thing is, I have:
BRLTTY 5.4 rev unknown [http://brltty.com/]
brltty: Log Level: none
brltty: Copyright (C) 1995-2016 by The BRLTTY Developers.
brltty: BrlAPI Server: release 0.6.5
brltty:    Copyright (C) 2002-2016 by Sébastien Hinderer <Sebastien.Hinderer@ens
-lyon.org>, Samuel Thibault <samuel thibault ens-lyon org>
And I also installed liblouis:
./lib/pkgconfig/liblouis.pc
What's happening here?
