GLUT and MESA are both installed on my machine, but I cannot seem to force the compiler to recognize the glut libraries.
gcc -lm -lGL -lGLU -lglut -lXmu -lXext -lX11 -o slices slices.o integral.o expint.o fluence.o
/usr/bin/ld: cannot find -lglut
collect2: ld returned 1 exit status
make: *** [slices] Error 1
