[BRLTTY] Orca Fails to Find BRLTTY and Liblouis

[Rob]

Today I  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:
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 at ens
-lyon.org>, Samuel Thibault <samuel.thibault at ens-lyon.org>
And I also installed liblouis:
./lib/pkgconfig/liblouis.pc
What's happening here? Do I need to twak Orca's configure script to find BRLTTY correctly?
