First, you need to install lang/clang34 (clang depends on llvm, not the other
way around).

You can have multiple compilers (and multiple versions of compilers) installed
at the same time. Anything installed from ports will *never* overwrite anything
in base. You're looking for clang34 (/usr/local/bin/clang34). Similarly, gcc
installed from ports would be the same: gcc 4.7, for example, would be
/usr/local/bin/gcc47. If you want to build ports with an alternate compiler,
you'll need something like this in make.conf:
