Unable to build on OSX 10.7 when linking with MKL

I don't know if this is an OSX 10.7 problem or a general OSX problem -- I have 
a feeling it is the latter.  Configuration is OSX 10.7.1, llvm-gcc-4.2, Python 
2.7.2, Intel MKL 10.3 Update 5

I have edited the site.cfg file to point to my install of Intel MKL:

[mkl]
library_dirs = /opt/intel/mkl/lib
include_dirs = /opt/intel/mkl/include
mkl_libs = mkl_solver_ilp64, mkl_intel_ilp64,  mkl_intel_thread, mkl_core, iomp5

However, the build fails with:

....

....

So It looks like --rpath is not supported on OSX.  Editing setup.py, I changed 
the reference from "--rpath" to "-rpath":

rpath_link = '-Xlinker --rpath -Xlinker %s' % library_dirs     

OSX's gcc can now build interpreter.so, however the relative paths are still 
not included correctly.  The only way numexpr will work is if DYLD_LIBRARY_PATH 
is set to the path where the Intel MKL libs reside.  However, setting 
DYLD_LIBRARY_PATH is definitely not recommended in OSX as it breaks just about 
everything.  

I'm not sure of the recommended solution in OSX for relative paths - but I'm 
sure there must be one.
