Bug details

Describe the bug

The Fix in 6c3a886 has the consequence that pip must be available on the system. On some systems of mine that isn't the case.

Steps to reproduce the bug

Run the Forumula on a system without pip.

Expected behaviour

I'm not sure if this formula should handle installing pip, but it's worth mentioning.

Attempts to fix the bug

You could install pip manually or with a separate state.
