That's indicative of something weird going on. configure should have 
looked for this library and found it. Nonetheless, it's only used in one 
utility in GROMACS (ngmx) and there are plenty of other bits of 
visualization software that can replace it. One work-around is simply to 
"configure --without-x --and-your-other-options" and GROMACS will not 
attempt to build ngmx, and not require this library for the rest of the 
installation.
