--- Comment #55 from Peter Dyballa <Peter_Dyballa at web dot de> --- Re-activating GCC15 requires llvm-3.3 although llvm-3.4 is installed, but de-activated. I threw llvm-3.3 away since I had llvm-3.4 – what will not work with llvm-3.4? I do not want to waste time, disk space, and energy so I am going to kill the build process for llvm-3.3 and change Portfile(s) that require llvm-3.3.
