[ros-users] 3rd party libs

[Andreas Hermann]

Hi Radu, hi Romain,

thanks for your quick and helpful responses. The main problem was that I 
used the precompiled Ubuntu release and so I had no idea of the 
svn-structures. It is still a bit confusing, where to search for the 
different packages, but I found the deprecated_msgs I need for the 
Swissranger (:
Still got some compiler errors in point_cloud_converter but I think 
thats a minor problem with incompatible checkouts (see below).

And thanks for the nabbble hint.

Cheers,
Andreas
