pip install did not build

[nguy]

I tried installing this package through the pip install pytmatrix method. The .so file failed to compile. However, installing from source after cloning the repo worked.

Running MacOSx 10.11.6
pip 8.1.2

Anyone else having this issue? I am trying to incorporate PyTMatrix into a conda environment with

#export COIN_INSTALL_DIR=/Users/USERNAME/CONDA_DIR/envs/houston
#eg export COIN_INSTALL_DIR=/Users/scollis/anaconda3/envs/houston
name: houston
channels:
  - conda-forge
  - defaults
dependencies:
  - python=3.6
  - cython
  - numpy
  - scipy
  - matplotlib
  - jupyter
  - xarray
  - netcdf4
  - nose
  - basemap
  - trmm_rsl
  - wradlib
  - cartopy
  - coincbc=2.9.9
  - pandas
  - ffmpeg
  - pip:
     - git+https://github.com/jjhelmus/CyLP.git@py3
     - git+https://github.com/ARM-DOE/pyart
     - git+https://github.com/CSU-Radarmet/CSU_RadarTools.git
     - git+https://github.com/jleinonen/pytmatrix
     - git+https://github.com/EVS-ATMOS/arm_sapr_tools
     - git+https://github.com/openradar/TINT

and I get

I would use the conda build for now instead of the pip build. Otherwise you'll need to make sure you have gfortran installed. (I think brew has it under gcc).
