Well, not entirely:

"configure" should be filling in OPENGLULIB by itself.

It depends whether NVIZ is linked against shared Mesa libraries.

It's the bit immediately before this which is relevant. The above are
the last two lines of the program which is used to check for libGLU. 
What's required are the compile command and its error message, which
immediately precede the program.

NVIZ doesn't require the GLw or GLwM libraries, which is what this is
checking for.
