[ros-users] gazebo compile problem with avformat lib

[Eric Perko]

What repositories and updates settings do you have enabled? I recently
had a similar looking error on a system that was running 9.10 with all
the update settings enabled in Synaptic (including karmic-backports,
which I suspect to be the problem). If you have changed the update
settings, can you try is on a 9.04 system that doesn't grab updates
from backports?
