I had the same problem using os x on a powerpc.

I thought it might be the version of ODE, I was using 0.8 so I used an older version (0.5), but then I had other problems. Then I gave up. If you find a solution, I'd love to hear about it.

Hello,

I'm trying to use Gazebo on an Intel Mac under OS X 10.4.9. After  
meddling with the build, and removing the --export-dynamics flag, I  
managed to build it and I am able to run the terrain.world example.  
However, I have been unable to run any of the other examples, where I  
get the following two different errors (depending on the world I try  
to use).

For instance, with example.world I get:

** Gazebo 0.8.0 **

With all other examples I get:

* Copyright 2000-2005 Brian Gerkey, Richard Vaughan, Andrew Howard,

Any ideas of what might be going on?

Many thanks for the help!
