Hi Nick,

I just released ros-indigo-ocl version 2.8.2 that has the latest Lua fixes:
https://github.com/ros/rosdistro/pull/10114

Actually we overlooked the rttros Lua module when we tried to move
everything that is related to ROS out of the core toolchain packages into
rtt_ros_integration <https://github.com/orocos/rtt_ros_integration> for the
2.7 release. I don't think it is necessary anymore for new code, as the
preferred way of finding ROS packages is the "find" operation in global
service "ros" installed by the rtt_rospack package:

depl:import("rtt_rospack")
path = rtt.provides("ros"):find("my_pkg")

I opened an issue for ocl here:
https://github.com/orocos-toolchain/ocl/issues/36
