So LLVM 3.0 has been released, and I’d like to use it on my Ubuntu 11.10 system. On the LLVM Download Page, there are tarballs for LLVM+Clang 3.0 built for Ubuntu 11.10 (and 11.04, and other systems) in x86 & x86_64 flavors. I see that 12.04 will have LLMV 3.0 from the package manager, but there do not seem to be any PPAs with the new version for older Ubuntu releases, nor is 3.0 available in the back-ports.
I could, I suppose, unpack the tarballs into
/usr/local, and then remove it if/when “offical” back-ports become available, but is that my best option?
