The only solution is to unset ROS_ROOT. autoproj will also use ROS_ROOT when
set.

Once ros is installed on your system, it's recommended to build the Orocos
toolchain with ros support and put your Orocos toolchain tree in the
ROS_PACKAGE_PATH.

We're still tuning the ros + autoproj / bootstrap builds, so don't hesitate to
drop us a mail if you run into a problem.
