These are preserved libs, it doesn't install non-_r libqhull.so.* at all from what I can see. I see a few issues from a quick look: - soname changed - qhull has no subslot for matplotlib to use - "libqhull -- Deprecated, shared library for non-reentrant Qhull (use libqhull_r or libqhullstatic)", from qhull's CMakeLists.txt - all in-tree versions of matplotlib are using the deprecated library For now I suggest to just stick to qhull-2015.2 until sorted out. Oh and, next time, please include emerge --info too.

Reading: https://github.com/qhull/qhull/blob/master/src/libqhull/DEPRECATED.txt Not ideal but sounds like the old library can still be used if really needed.
I can confirm the bug. I masked qhull 2020.2. Emerged qhull 2015.2 and then emerge matplotlib worked again.

We can expose the deprecated library as Arch has (I was reluctant at first but then I saw it'll be supported indefinitely): https://github.com/archlinux/svntogit-packages/commit/13e306e999def5c54614fa28b041181bdbb81a56#diff-3e341d2d9c67be01819b25b25d5e53ea3cdf3a38d28846cda85a195eb9b7203a. I just need to figure out how to properly build an extra target with cmake.eclass.
