Try 'make clean'.

I had similar problem (with r300g) ,

In fact glxgears did not load the right mesa lib
despite a good ldconfig -v (added new mesa path 000_mesa.conf)

do:
ldd /usr/bin/glxgears
it should show the path of the lib used by the app
if it is wrong and you use natty or another ubuntu
a temporary fix is:

sudo rm /etc/ld.so.conf.d/GL.conf (symbolic link to original mesa)
sudo ldconfig

don't know the right fix though

Comment 3 Alexandre Demers 2011-04-17 09:22:02 UTC

If ldd confirms you are using the good library, have a look at the following bug:
https://bugs.freedesktop.org/show_bug.cgi?id=36282

It may explain the problem. Otherwise, watchout for Natty, things are a real mess because drivers are now installed under the multiarch folder, but the dev files are installed in a different folder. So if you just compiled and installed like you were doing in previous Ubuntu version, you will end up in a dead end. I had to work a bit to figure everything out.

Comment 4 Ian Milligan 2011-04-18 07:33:20 UTC

Interesting, I'm using LD_LIBRARY_PATH and LIBGL_DRIVERS_PATH I don't think that is the problem. It's only glxgears having this problem, however, so that problem may be with it.
