linking failure

I have llvm 3.5 installed from source in /opt/llvm35
I've made symlinks to the binaries in /usr/bin

They look like this:

$ ls -l /usr/bin/ | grep clang
clang35 -> /opt/llvm35/bin/clang
clang++35 -> /opt/llvm35/bin/clang++

Then if I compile a simple c++ program, the clang compiler fails to link it.
See the attachment for the build log.

If I rename the clang++ symlink to either clang++ or clang++-3.5 it works fine
