I'm trying to use gmpy2 as part of my Python packages in Heroku but I'm having issues with the building process.
I'm using two different buildpacks: the standard Python buildpack and APT (heroku-buildpack-apt) so I can install the dependencies for:
- libmpfr-dev
- libmpc-dev
- libgmp-dev
- libgmp3-dev
This is the error from the build log:

What should I be looking at? Can I use flags for the gcc command with this buildpack?
