pip3 install pandas--error: command 'gcc' failed with exit status 1
I’m getting an error trying to install pandas via:
-bash-4.3$ pip3 install pandas

I had issues installing numpy previously, and the numpy folks had me set a flag to get around that.  I don’t know if something similar would be required here.  https://github.com/numpy/numpy/issues/11317

The entire stack trace is 15K lines.  I can attach the whole thing if it will help.  I'm including the last bit below.
