Orca Using 's braille support with brltty 3.8-dev

[Hermann <steppenwolf2 onlinehome de>]

Hi to all,
because it offers support for Speech-dispatcher, I installed the developer 
version of brltty, so I can use a German synth with brltty in text 
mode.
However: This version of brltty does not support braille in Orca.
Dave Mielke told me to install a developer version of Orca, so that braille 
support is back.
1. Does the developer version of Orca indeed suport brltty 3.8-dev?
2. If so, what must I do to install this version? For brltty I had to set 
up Subversion. Can I get Orca over this service, or do I have to install a 
different service like CVS? If this is the case, how can I do this?
Regards
Hermann
