"gluBuild3DMipmaps is only available if the GLU version is 1.3 or 
greater", mostly likely the system on which you are running has a GLU 
version less than 1.3.

 >>> from OpenGL.GLU import *
 >>> gluGetString( GLU_VERSION )
'1.3'
 >>> gluBuild3DMipmaps
<CFunctionType object at 0x2aaaab8c8a78>
 >>>

Or it could be that you're running on a platform that has some strange 
semantics surrounding access to GLU features for versions > 1.0.  Above 
session is from a modern Linux desktop.

Good luck,
Mike
