Do you have this library? IIRC, Mesa doesn't build it by default; you
have to build it separately.

Also, whilst recent versions of XFree86 provide the correct
functionality, the Motif versions are included in libGLw, rather than
being in a separate library. Furthermore, the "configure" test won't
find the necessary function (GLwCreateMDrawingArea) because it is a
macro.

Do you have UnixODBC installed? iODBC won't work.

You have two conflicting sets of OpenGL headers installed, in
/usr/local/include/GL and /usr/X11R6/include/GL.

This is coupled with a bug in r3.showdspf.openGL, in that it includes
OpenGL headers without using the "GL/" prefix, and a complementary bug
in the build process, which is using /usr/local/include/GL as the
include path.

Either temporarily remove one of the sets of OpenGL headers, or don't
try to build GMSL.

No; PostgreSQL doesn't provide an sql.h file.
