python setup.2.py build: aspell.h not found

[harryHoward]

On Mac OSX 10.13.6 (High Sierra) with Miniconda Python 2.7.15, I download and ran the build command but gcc failed due to the lack of aspell.h.

My Miniconda directory (to which setuptools should be sending everything it builds) has an include sub-directory, but aspell.h is not there; in fact, I can't find it anywhere on my hard drive.

I also tried "pip install aspell-python-py2", which also failed with the same error.
