Bug description

After cloning the repository and following the steps in BUILDING.md, I encounted the Python error SSL: CERTIFICATE_VERIFY_FAILED when running the make dependencies step.

I've opened a PR with a proposed fix here: signalapp/Signal-Pods#9

Steps to reproduce

• Open a shell environment where only the system python3 is available
• Clone the repository following the steps in BUILDING.md
• Run make dependencies

Actual result: Setting up dependencies fails with a Python 3 exception.

Expected result: Expected dependencies to be set up.
