[ros-users] Problem with sicktoolbox.

Did you install these for use yourself?  The boxturtle install shouldn't be
using them even if they're installed.  I just installed boxturtle alongside
ogre 1.6.1 on a Karmic box and it works fine.  What happens if you uninstall
those versions of ogre?

This usually implies you're running either: a) without a graphics card that
supports hardware acceleration, or b) with the wrong drivers.  See
