Matt,

I'd update the commit message to mention that that libglapi.so, 
libGL.so, libGLESv2.so, libGLESv1_CM.so must all come from the same 
version of Mesa or bad things may happen.

Otherwise, I don't see a problem with it.  Tightly-coupled versioning 
between the libGL* libraries should be fine, and this doesn't affect the 
loosely-coupled versioning between libGL* and the DRI drivers.

Also, I believe the shared-glapi option is necessary for apps that use 
both GL and GLES.  I've been building with it for some time now; I'm 
pretty sure I needed it for apitracing GLES apps.
