[ros-users] rosinstall problems on Debian

Debian installation is quite new and might not work on every installation
(that's why there is a WORK IN PROGRESS on top of it ;) ). Please do not
hesitate to share your problem here, you'll receive help and you'll help
Debian becoming a fully working installation.

Yes Squeeze is officially a stable version for a week, so now, lenny may be
(IMO) considered as an "old install".

If you dare, I suggest you to try the next coming version of ROS because
dependencies are better managed. It is currently in a release candidate
state, so it's close to be the new newest version.
