Reading the installation instructions for the compiler it is not clear to me if the new binutils version are only a compile time requirement or also a requirement at runtime.

Hope you can help me.
With best regards
You will need the latest version of binutils because they have the necessary requirement to use the newest Bulldozer based cpus. Use binutils 2.21 or later for the best performance. I havent understood why you needed to back port them though! You should be able to use the Open64 compiler binaries on Wheezy and let me know if you have any issues there.
