[06:51:19]  <@sam_> mgorny, ztrawhcse: http://sprunge.us/YD7KGa works for me (s/BUILD_DIR/WHEEL_BUILD_DIR/) (easy tester is to try emerge scipy[fortran] w/ meson-python installed but not pythran). but i don't think we want to do WHEEL_BUILD_DIR, so I guess our choices are WHEEL_BUILD_DIR/.. or export BUILD_DIR as well. i prefer the latter
[06:51:29]  <@sam_> anyway please push it once you decide what you prefer

    distutils-r1.eclass: ensure meson-python uses a stable build directory
    
    When not passing an explicit build directory, meson-python configures
    meson into a build directory that is rooted in a tempdir with a random
    suffix. This results in unstable paths, which currently disappear after
    meson-python completes (either with success or failure). It doesn't
    handle incremental or resumed builds, and it's very difficult to debug
    -- for example by inspecting the logfile that meson itself prints out
    when the configure stage fails.
