I'm setting up the Mesa demos repo on a new system. autogen.sh fails

GLEW in the demos tree itself.
Dan, can you fix that?

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:

I wrote a test program that just calls glewInit() and compiled it with 'gcc
foo.c -lGLEW -lGL -o foo' and it worked fine.
I'm traveling right now, but I believe the problem is that mesa does
not install a glew.pc pkgconfig file. You can create one from the
glu.pc example (or one of the others) and install it in
/usr/lib/pkgconfig (for x86) or /usr/lib64/pkgconfig (for x86-64).
The check for glew in the demos configure script would be something like:
PKG_CHECK_MODULES([GLEW], [glew])
This would search for glew.pc and then the flags would be stored in
GLEW_CFLAGS and GLEW_LIBS.
I don't have a chance to fix this for another week or so, but it needs
a little fixing on the mesa side for glew to be a fully installed
library like gl or glu.
Well we don't generally install glew from Mesa, we use glew from
upstream in Fedora for example, it now install a pc file, since 1.5.4
I think.
Just FYI: I just installed the latest Fedora 13 this week and glew is
at version 1.5.2. There was no .pc file in the RPM.
