build fails with a bogus missing dependencies list #504

I am trying to build a wheel with build for the scanpy project.

It prints this error message:

*** Error code 1

Many dependencies that it lists are installed: py39-anndata-0.8.0 py39-matplotlib-3.4.3_3 py39-kiwisolver-1.4.3,1 py39-umap-learn-0.5.3 py39-seaborn-0.11.2

There is one real problem: threadpoolctl is missing.

But why does build complain about dependencies that are installed?

py39-build-0.8.0 FreeBSD 13.1

Ran into this problem as well, building https://github.com/john-hen/Flake8-pyproject on a system that brokenly had pycodestyle 2.11.1 and flake8 7.1.1 installed -- build complained that it couldn't find the pycodestyle 2.12.1 dep, and it took stepping through the code with pdb to discover the installed version was incorrect.

At the very least, a --verbose option listing, for each (transitive) dependency, who asked for it and what version was found, would've gone a long way towards easing this archeology.
