./configure can't find glut.h - I installed mesa in a local dir /home/www/barton so glut.h is in /home/www/barton/includes/GL instead of the default /usr/includes/GL/

when i run ./configure with these options:
./configure --prefix=/home/www/barton --with-glut=/home/www/barton/include/GL --with-gl-libs=/home/www/barton/lib --with-gl-inc=/home/www/barton/include/GL --with-glut-libs=/home/www/barton/lib

it still says it can't find it.
here's a quick look at what i am seeing:
checking GL/gl.h usability... yes
checking GL/gl.h presence... yes
checking for GL/gl.h... yes
checking for glNewList in -lGL... yes
checking GL/glu.h usability... yes
checking GL/glu.h presence... yes
checking for GL/glu.h... yes
checking for gluLookAt in -lGLU... yes
checking GL/glut.h usability... no
checking GL/glut.h presence... no
checking for GL/glut.h... no


it seems to be checking the default /usr/include dir which has glu.h (which passes configure's check) but not glut.h

any suggestions?

Check your config.log for the exact error, you'll also see which directories are actually used.

i checked the config.log and fixed the directory (it added the GL so i had GL/GL/) thanks -
but here's a knew glitch:
It finds glut.h but the preprossesor rejects it.
checking GL/glut.h usability... yes
checking GL/glut.h presence... no
configure: WARNING: GL/glut.h: accepted by the compiler, rejected by the preprocessor!
configure: WARNING: GL/glut.h: proceeding with the preprocessor's result
checking for GL/glut.h... no
configure: error: No glut.h found. See INSTALL file for details on correcting this problem.
it looks to me like gcc can't find the file - but i don't understand why not.
here's the excerpt form the config.log:
