Hi!

I'm trying to setup ROS Groovy on Ubuntu 13.04 Raring (some of the hardware is not supported by Precise). As Groovy binaries are not planned for Raring, I am doing this from source following the instructions at on the ROS wiki.

When it tries to build Gazebo, it fails with a checksum mismatch.

Any ideas how to solve this or get around it (Gazebo is not critical for me at the moment, but it would be nice to have everything setup and running)...

Thanks!
