jaraco-functools was updated recently to be built with flit instead of setuptools. As a result at least one package, dev-python/cheroot, does not run anymore, instead giving the following error when starting up: pkg_resources.DistributionNotFound: The 'jaraco.functools' distribution was not found and is required by cheroot mgorny tracked this down to discrepancies in how build tools respect non-alphanumeric characters in wheel files. The older PEP 376 [1] states that name is converted to a standard distribution name by replacing any runs of non-alphanumeric characters with a single '-'. but was never fully implemented by the standard libraries, instead finding a place in third-party tools. This was then superseded by a different standard for wheel files. Currently [2], "In distribution names, any run of -_. characters (HYPHEN-MINUS, LOW LINE and FULL STOP) should be replaced with _ (LOW LINE) [..]". However, since older tools relied on an older standard, a full stop _must_ be accepted by them. When installed by setuptools, jaraco-functools is installed with a full stop. When installed by flit, jaraco-functools is installed with an underscore. To find its own version [3] cheroot uses pkg_resources which does not support new replacement rules of wheel files and therefore fails to load with the new version of jaraco-functools.

Install dev-python/cheroot 2. Try running 'cheroot' from a shell Alternatively, without installing dev-python/cheroot: 1. Open up a python REPL 2. Run the following: import pkg_resources; pkg_resources.require('jaraco.functools') Actual Results: cheroot crashes with "pkg_resources.DistributionNotFound". See full log in attachment. Expected Results: cheroot starts up

I removed the "fix" from the ebuilds, and could emerge the packages again.
(I suspect the issue was actually because of the now reverted eclass change?)
