Can someone help with this?  When I install and try to run Gazebo I get the following error:

[cbeane@ncslab worlds]# gazebo example.world

  Minor opcode of failed request:  16 (X_GLXVendorPrivate)
  Serial number of failed request:  23
  Current serial number in output stream:  24




I first installed librtk-src-2.30, then player-1.6.5 and then stage-1.6.2.  And all went well.  But when I first tried to install Gazebo it kept complaining about not being able to find gl.h, glu.h and glut.h.  So I installed Mesa-6.4.1 and all of it's dependent packages.  I ran configue as such (./configure --includedir=/usr/local/include/GL).  It apears to have installed with no errors and this is what happened when I tried to run Gazebo.


Can anyone help???
