Hi,
I am building the master branch.
I am using :
Ubuntu
Version 12.04 (precise) 32 bits
Kernel Linux 3.2.0-60-generic-pae
GNOME 3.4.2
The output of clinfo is in the attached file.

Please share the output of clinfo and your exact system (e.g. OpenSuse
AMD drivers for example are known to be problematic).
