It is definitely the problem.  You should be linking with the shared GL.
-Zg is maintained for backward compatibility.  Instead, link your program
with "-lgl_s".  Besides providing a binary compatibility, linking to the
shared library will also reduce the size of your executable since it won't
have its own copies of the GL routines.

smelled rather ripe.
