[SciPy-Dev] Building SciPy from source for development

[Isabel Kaspriskie]

Thank you everyone! The only things I had to do differently:

   - Renamed miniconda3/lib/libgfortran.so
   - apt installed g++

In my build output, I saw that I was using both g++ and gcc, and I'm not
sure why that might be, but the build was successful and tests ran fine.

Cheers,
Isabel
