Yes, -std=c++11 was added with gcc 4.7, earlier versions fail with this switch.
Because the actual Ubuntu 12.04LTS still use gcc 4.6, I did the custom.pro hack to replace it with -std=c++0x.
I tried to use both switches, trusting the unknown switch is ignored by gcc, but with that combination all gcc versions failed. I've checked this with gcc 4.6 and 4.8.
