I just found a bug report from the end of September detailing the exact same problem: https://bugs.python.org/issue34823 It's still open with no comments at all :( Is there a chance this will be fixed? Summarizing: the problem is that python can't be build on linux from source if libffi is installed to non-standard directories.
