Clarify MKL compiling and linking process about caffe HOT 2 CLOSED

Just a note that -m64 wasn't required for me to get a successful OS X build.
I've written up the process at the bottom of this: http://caffe.berkeleyvision.org/installation.html

The MKL library licensing does include redistribution of the library .so and .la files: http://software.intel.com/en-us/articles/which-intel-math-kernel-library-intel-mkl-libraries-are-redistributables. We have the option of distributing precompiled binaries if we so choose.

Lack of auto-configuration aside, our build and linking of MKL work. The dynamic linking documentation you referenced seems to be only for Windows, so we don't need to worry about mklvars.sh.
