PyOpenCL Install Trouble on Mac OS X El Cap 10.11.3 with Enthought Canopy 1.6.2.3262

Question

Versions: pyopencl 2015.2.4 Mac OS X 10.11.3 Xcode: 7.2.1 Enthought Canopy 1.6.2.3262

I am trying to install PyOpenCL on Mac OS X 10.11.3 with Enthought Canopy and I am having difficulty. Following directions on the PyOpenCL wiki:

python configure.py make

I get the following output:

rovitotv-mbpr15:pyopencl-2015.2.4 rovitotv$ python configure.py
rovitotv-mbpr15:pyopencl-2015.2.4 rovitotv$ make

After playing around with the Canopy package manager I was able to get pyOpenCL built and running on my Mac. The solution I came up with was I went into the Canopy Package Manager and updated cffi. After the cffi update I just reran the build and install steps as documented on the pyOpenCL wiki . After the install I ran a number of PyOpenCL examples. Thanks!
