graphics/gle fails to build after Mesa update

[David Brownlee <abs%absd.org@localhost>]

        It fails with:

configure:9478: checking for glutSwapBuffers in -lglut
configure:9509: cc -o conftest -O2 -pipe -I/usr/pkg/include -I/usr/include 
-Wall -I/usr/pkg/include -I/usr/include -L/usr/pkg/lib -Wl,-R/usr/pkg/lib 
-L/usr/lib -Wl,-R/usr/lib conftest.c
-lglut  -lSM -lICE -lXmu -lXi -lXext -lXmu -lGLU -lGL  -lX11  -lXext -lm >&5
/var/obj/pkg/graphics/gle/work/.buildlink/lib/libglut.so: undefined reference 
to `glXGetProcAddressARB'
configure:9512: $? = 1

        Interestingly glut appears to be linked with libGL which contains
        glXGetProcAddressARB.  Anyone seeing similar?
