Digging deeper...  The issue is actually in the configure script (I 
think).  Even after copying libGLEW.a from Mesa 7.8.2 into 
/usr/lib/libGLEW.a (which is the same as /usr/lib64/) configure is 
failing:

[...]
checking pkg-config is at least version 0.9.0... yes
checking for GL... yes
checking GL/glut.h usability... no
checking GL/glut.h presence... no
checking for GL/glut.h... no
checking for glutInit in -lglut... no
checking for GLEW... no
checking GL/glew.h usability... yes
checking GL/glew.h presence... yes
checking for GL/glew.h... yes
checking for glewInit in -lGLEW... no
configure: error: GLEW required

I wrote a test program that just calls glewInit() and compiled it with 
'gcc foo.c -lGLEW -lGL -o foo' and it worked fine.
