[Mesa-dev] RC3 build problem

[Marty Jack]

Line 1243 of configure.ac says
    if test "x$enable_dri" = xyes; then
and enable_dri is nowhere defined.  In RC2 the equivalent line said
    if test "$mesa_driver" = dri; then
I do not know what the appropriate test is.

This results in gbm_dri not being compiled, results in gbm_dri_backend not being defined, results in applications not starting because the .so won't load successfully.
