Installer doesn't create llvmlite/binding/libllvmlite.so library in venv

My setup: Python 3.5.2, virtualenv, Ubuntu xenial, llvm 4.0, newest pip and distutils:

(env) skodajan@jan:/tmp$ LLVM_CONFIG=/usr/bin/llvm-config-4.0 pip install llvmlite
Collecting llvmlite
  Using cached llvmlite-0.17.0.tar.gz
Installing collected packages: llvmlite
  Running setup.py install for llvmlite ... done

Once I install numba, the import numba fails:

(env) skodajan@jan:/tmp$ pip install numba

I have a similar problem with the following setup: MacOS 10.11.3, Python 3.6.0 virtual environment, explicitly specified environment variables LLVM_CONFIG and MACOSX_DEPLOYMENT_TARGET. Running pip install llvmlite --upgrade attempts to install llvm 0.17.1, but then throws the following error:

Traceback (most recent call last):
    File "<string>", line 1, in <module>
    File "/private/var/folders/k9/mxm_jrl50m75kmgvdk9_wlh00000gp/T/pip-build-1bk4oqiv/llvmlite/setup.py", line 175, in <module>

      raise RuntimeError("missing {}".format(path))
  RuntimeError: missing llvmlite/binding/libllvmlite.dylib

(installation then proceeds to install llvmlite, however the installed module is not usable)

@leftys , I am temporarily hosting the wheel on anaconda.org. You need to install it with the following command:

pip install -i https://pypi.anaconda.org/sklam/simple llvmlite

If you can confirm it working, I will move it to PyPI.

(Note: I have to stage it in anaconda.org because PyPI won’t allow a file to be re-uploaded)
