To generate the configure file from configure.ac, use the following
./autogen.sh - This command will create the configure script and run
it with some default arguments. You can re-run the configure script with
your preferred arguments later if you want.
./bootstrap - creates the configure
You will need to have GNU autotools installed on your system.

Information on diracvideo.org is current and is used by Schro and Dirac
developers. So I suggest you use the document available there.
BTW, if you have any further questions related to Dirac and/or
Schroedinger implementations I suggest that you post them to the Dirac
developer forum ( http://sourceforge.net/forum/?group_id=102564 ) or
Schro mailing list
That way other Dirac/Schro developers will be able to answer your
queries more quickly. The Dirac/Schro IRC channel #dirac is also very
active depending on the time of the day where the developers live.
GStreamer Plugins for wrapping Dirac in Ogg are available in the gst
sub-directory of the Schroedinger source. It might be a good idea to see
how they've handled it there.
It will be great to have Dirac in Ogg support in FFmpeg.
