Can't get pyjwt to work on remote

[blockjon-dd]

I'm not sure what I'm doing wrong, but pycross+PDM is proving to be extremely challenging when I use buildbuddy.

When I do a local build like this:

bazel build //services/cicdtools/src/python/app:github

things work.

When I do a remote buildbuddy execution, it fails:

bazel build --config=remote //services/cicdtools/src/python/app:github

Been trying everything I can think of but this just does not want to work. I think I had this working when I was experimenting with the poetry integration, but PDM seems like a better tool and I'd love to be able to get this to work.

This all stems from my attempt to try to use the pypi library called pyjwt.

It looks like this is failing to build cffi from source, and you don't have setuptools specified as a build dependency for that package.

Instead of specifying dependencies per package, try setting default build dependencies for the whole lock file, which is a relatively new feature. See here for an example.
