Also don't use rec { foo = bar; }, use (finalAttrs: { foo = finalAttrs.bar; }) instead.

The diff looks good, but why is it failing to build?

I'm not exactly sure. We saw the same failure here: #302488

Also, the Darwin build fails. I do not have a MacOS nor a BSD machine at hand to prove that the builds work for these platforms, and I'd rather not test it with ofborg in my development-build cycle. Do you have strong opinions against marking this broken for Darwin and BSD for the time being?

No, for me it's fine.

@katexochen the issue you pointed out should be fixed now.
