 compile fails with this error

 {{{

 }}}

 include/GL/mesa_glinterop.h
 has a block where it appears that
 glx.h is not expected to be included
 {{{
 /* Forward declarations to avoid inclusion of GL/glx.h */
  typedef struct _XDisplay Display;
  typedef struct __GLXcontextRec *GLXContext;
 }}}

 However it will be included if Apple GL headers are used
 so, I patched it there to stop the double reference
 it seemed logical to test for definition of

 {{{
 #ifndef APPLE_GLX_CONTEXT_H
 }}}

 Then it built and installed for me

 {{{
