MAC OS Catalina(10.15.1) seems to have created some problems for building code that uses gcc. I am trying to build a python application which is running into the following error.
Running setup.py install for pdftotext: started

Complete output from command /usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-yzaiz97e/pdftotext/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-67h0h5_9-record/install-record.txt --single-version-externally-managed --compile:

Any help to debug the issue would be appreciated.
