In the 'ocl' toochain-2.2 branch: did you try a 'git pull origin' or 'git pull 
autobuild' (depends if you did a manual install or bootstrap script) ?

On the orocos_toolchain_ros-0.2 branch, did you try a 'git submodule update' 
to get the latest rtt/ocl version ? (may also require a 'git pull origin' to 
get the latest ros updates).

Hope this helps,
Peter
