The installation of PyECLOUD, PyHEADTAIL and other related libraries on MAC-OS can be difficult due to compatibility issues with compilers and libraries.

Recommended method

The most robust solution is to use a linux virtual machine (Ubuntu is recommended). A recipe to setup a virtual machine can be found here.

Alternative method

The code might run with a full anaconda installation. After installing Anaconda and before installing PyECLOUD, PyHEADTAIL etc. it is necessary to get a fortran compiler. For this purpose please type:

conda install gfortran_osx-64

See also this recipe (more recent) that works for for PyHEADTAIL (not tested on PyECLOUD).
