libGL error: dlopen /usr/lib/xorg/modules/dri/r600_dri.so failed (/usr/lib/libglsl.so: undefined symbol: hash_table_string_hash)

Is /usr/lib/libglsl.so built from your Mesa tree? Generally check that r600_dri.so, libGL.so.1 and any binaries they link against are picked up from your Mesa tree for the bisection.

(In reply to comment #30)

In order to get rid of the latest compile problem I upgraded libgl to the 9.0.1 version. Now gnome starts and does not show the problem.

So that got rid of the undefined symbol above? Hmm. Sounds like it was/is not picking up all relevant binaries from your Mesa tree.
