One of the issues:

https://lists.yoctoproject.org/pipermail/meta-ti/2012-February/000491.html

I haven't tried if either 3.0 or a pending 3.1 update for Panda (from 
omapzoom/ti-ubuntu), resolve this gcc-4.6 build issue. But either way I 
believe there was something else with one of our components not building with 
gcc-4.6 - SGX or multimedia, don't remember exactly.
