If you have conda you can create a dedicated environment with
conda create -n pysit python=2.7
source activate pysit
Then install the dependencies
conda install numpy
pip install pysit --pre
pip uninstall pysit # Keeps the dependencies we need
pip install matplotlib==1.4.3 obspy==0.10.2 ipython==5.0.0
Clone the repository and
python setup.py build
python setup.py install
You can checked wether the installation is ok by running examples.
We experienced troubles on OSX Yosemite at building time, openMP was not supported by clang. To solve that problem, we installed gcc5 with Homebrew.
On OSX with conda4.4.10, the default available gcc4.8.5 solved the problem.
