I build Mesa with OSMesa from git source for testing VTK on two hosts with:

./autogen.sh \

   --enable-dri \
   --enable-shared-glapi \
   --enable-gallium-llvm \
   --with-gallium-drivers=nouveau,swrast \
   --enable-osmesa

When I used Fedora 17 OSMesa used :

GL_RENDERER: Gallium 0.4 on llvmpipe (LLVM 3.0, 128 bits)

I updated the OS on each host to Fedora 18 on different days.

After the update each host reverted to using the old OSMesa driver:

GL_RENDERER: Mesa OffScreen

I used to be able to change the driver by setting GALLIUM_DRIVER and I
can't do that anymore.

Can anybody give me a clue as to what's going on?

My guess is your Fedora 18 system is missing some dependency that was previously found on your Fedora 17 system.

I'd try to compare Mesa config.log files from 17 vs. 18 to see what might be different. Or, just the output from running ./configure on each.
