How may I compile a C++ program under the C++11 standard in Ubuntu 11.04 with the most up-to-date compiler, at best using compiler from the distribution, i.e., pre-built package.

How may I compile a C++ program under the C++11 standard in Ubuntu 11.04 with the most up-to-date compiler, at best using compiler from the distribution, i.e., pre-built package.
Update in 2017: It seem GCC 7 and higher has full C++ 2011 compliance. The rest of the answer below was written in the GCC 4.7 era, and was correct when written in 2011.
Strictly speaking, I can not offer you any 100% C++ 2011 compliant open source compiler, because there aren’t any that are 100% there yet.
It looks like you should stay with GCC for now, and GCC 4.6 binaries are included in recent Ubuntu distributions. C++ 2011 is incomplete in GCC 4.6 but contains a lot of 2011 stuff, more than Clang+llvm. It’s more than 90% C++ 2011 feature complete. GCC 4.7 contains yet more stuff, but I don’t see gcc-4.7 binary packages in Ubuntu 11.x yet, but you can check over here for another way to get gcc 4.7 binaries on ubuntu, or try AskUbuntu, a stackexchange powered site for ubuntu.
According to this page Clang+llvm does not yet offer full C++ 2011 standards compliance, either, and I haven’t done the exact math but I see a lot more “No” entries on Clang, versus Gcc.
