[Robotics] Blender Ubuntu 9.10 iTaSC branch build -> fail

[Florian Lier]

Hey,

ahh ok - sorry for double posting this.
I accidentily skipped reading this:

cd <itasc_dir>
cp config/linux2-config.py user-config.py
<edit user-config.py: python version, player off>
python scons/scons.py


Now blender 2.5 iTaSC builds successfully and I can load my .blend files.

Now :) tell me how to add the new IK Solver, I couldn't find it in the 
contraints
menu.

Florian
