mypy-0.740.ebuild: >=dev-python/psutil-5.4.0[${PYTHON_USEDEP}] mypy-0.740.ebuild: <dev-python/psutil-5.5.0[${PYTHON_USEDEP}] Please make it work with newer versions. Also, is there a reason to keep 9 versions?
You're right, it seems upstream changed the dependency on psutil as of version 0.710, so I've updated that for 0.740. I've also removed a bunch of old versions and bumped it to 0.750 in the process...
Fixed in commit cb3769134c64.
