Python (setuptools?) helpfully automatically downloads a temporary copy of the dependency to use, so we may not notice this until committing the port, at which point if we're looking at the buildbot logs we might notice that it fails to build on older OS versions because of SSL problems.

According to the setuptools docs, easy_install at least has a --no-deps
flag, and if that doesn't work, there's a --allow-hosts flag to which
you can pass None to prevent all downloading. Someone would have to test
whether these work when passed to setup.py as well.
