[ros-users] rosmake error

[Blaise Gassend]

I would focus on the error message you are getting. Why can't rospack
create the file /home/omnibot-user/.ros/.rospack_cache.6LDHUP.

Is it possible that you were running as root as some point, and that
/home/omnibot-user/.ros is owned by root? Try to create files in that
directory by hand. That should allow you to track down your problem.

I doubt that adding PowerCube to your rosmake invocation caused the
problem (it seems to be ignored when I try something similar).
