From mesa-8.0 git log: commit 34a28ccbf459ed5710aafba5e7149e8291cb808c Author: José Fonseca Date: Sat Jul 9 11:07:14 2011 +0100 glut: Remove GLUT source. Most distros ship freeglut, and most people don't care one vs the other, and it hasn't been really maintained. So it is better to have Mesa GLUT be revisioned and built separately from Mesa.
