Thanks, ill look into it. But it saw something to do with the problem. When i looked at the config terminal wndow- i saw this > checking for GL/gl.h... no > checking for GL/glx.h... no > checking for GL/glext.h... no > checking for GL/glu.h... no > The funny thing is- i tracked the files down in finder and they are there! They all are in /Developer/SDKs/MacOSX10.6.sdk/usr/X11/include/GL/ Is this my fault? where should they be?
