The culprit are two files in the RTT package that take ~ 900M each to 
compile. I asked on the orocos ML whether there was a way to "serialize" 
the build of these two files in CMake in a portable way, but with no 
results so far.

There is no need to switch on any branch. The current master is supposed 
to be compatible with ruby 1.9

The garbage collector in 1.9 is as bad (they are exactly the same), but 
the interpreter allocates less objects (so, in the end, it does behave 
better).

I run on Ruby1.9 ON THE ROBOTS, as -- as Matthias mentioned already -- 
there are no prebuilt QtRuby packages for ruby 1.9 (i.e. ruby 1.9 for 
headless things and ruby 1.8 for GUIs)
