clang linker error in new version of caffe

[Dmitry Yutkin]

When I do 

make all

I get this errors:
...

  "caffe::Net<float>::Forward(float*)", referenced from:
      test() in caffe.o
      time() in caffe.o
ld: symbol(s) not found for architecture x86_64

I have this error as well. If it's relevant, I'm building on OSX El Capitan, with CPU_ONLY option and using OpenBLAS. For the time being I've been using an earlier build from January, but I'm running into some Python issues that have since been fixed, so it'd be nice to be on the latest version.

I also tried to compile previous versions but they have issues with python wrapper (fixed in PL). If I use the newer versions, I face with compile issue from my top msg.
