Hi,

On FreeBSD -current,  clang 3.4 is now the default compiler.
Clang 3.4 rejects "-R/path/to/lib" flag (previously in version 3.3 it just ignored it).

This leads to some errors with some python extensions:

I found the patch below to help, it is for function runtime_library_dir_option in Lib/distutils/unixccompiler.py
-Wl,-rpath works for both gcc and clang on freebsd
