[ros-users] rosinstall problems on Debian

[Taylor Veltrop]

After upgrading to Debian 6.0 the rosinstall script works fine.

The new problem is that nothing would compile: "gcc fails to compile  
simple program"

gcc was linked to gcc-4.3 so I had to do a rm /usr/bin/gcc and ln -s / 
usr/bin/gcc-4.3 /usr/bin/gcc
Is there a more correct way of doing this?

Now things seem to be moving along.

This happened with both cturtle and diamondback by the way.
