[tuxracer-main] Can't Compile on RedHat 6.2

[root <ja...@ix...>]

Hello:
    I've been trying for sometime to get tuxracer to compile. The first
problem started when I ran ./configure and got an error saying I need
glext.h . That was very easy to get since a site was provided. After
./configure completed, I am told to run make. However, when make is
going through its process I get a error messages saying:

    gl-util.c:    In function 'init_opengl_extensions':
    gl_util.c:408 :   'glXGetProcAddressARB' undeclared <first use in
this function>
    gl_util.c:408:    <Each undeclared identifier is reported only once
    gl_util.c:408:    for each function it appears in.>
    gl_util.c:404     warning: 'get_gl_proc' might be used uninitialized
in this funtion

    make[2]: *** [gl_util.o] Error 1
    make[2]      Leaving directory '/root/tuxracer-0.60.1/src'
    make[1] *** [all-recusive] Error1
    make [1]     Leaving directory '/root/tuxracer-0.60.1'
    make: *** [all-recursive-am] Error 2
