(most of) customization options are documented there:
http://rock-robotics.org/autoproj/advanced/customization.html
In your case, you want to do
Autobuild.parallel_build_level = 4
in autoproj/init.rb
Could you send me the content of /proc/cpuinfo (I parse that to
autodetect the parallel build level)
Note: I prefer that general questions go on rock-dev, that makes it
easier for other people to find recurrent answers ;-)
