Patch up Caffe's paths to avoid need for DYLD_FALLBACK_LIBRARY_PATH on OSX El Capitan, which doesn't really support it anymore

fix_paths.sh

#!/bin/bash

CUDA_LIB_DIR=/usr/local/cuda/lib
CUDA_VERSION=7.5
CUDA_LIBS="cublas cudart curand"

CUDNN_LIB_DIR=/usr/local/cuda/cudnn-3/lib
CUDNN_VERSION=7.0
CUDNN_LIBS="cudnn"

CAFFE_ROOT=${1:-.}

for x in $(find $CAFFE_ROOT/build/ -name '*.bin' -o -name '*.so' -o -name '*.testbin'); do
    for lib in $CUDA_LIBS; do
        name=lib$lib.$CUDA_VERSION.dylib
        install_name_tool -change "@rpath/$name" "$CUDA_LIB_DIR/$name" $x
    done
    for lib in $CUDNN_LIBS; do
        name=lib$lib.$CUDNN_VERSION.dylib
        install_name_tool -change "@rpath/$name" "$CUDNN_LIB_DIR/$name" $x
    done
done

Potential users, note that BVLC/caffe#3227 (comment) is probably better, though it may need tweaking if you use cudnn in a different directory.
