There is the following instruction in caja-dropbox ebuilds: sed -e 's|\[rst2man\]|\[rst2man\.py\]|' -i configure.ac || die Now, this substitution is not necessary anymore, since starting with dev-python/docutils-0.21 it installs scripts with .py suffix: https://docutils.sourceforge.io/RELEASE-NOTES.html#release-0-21-2024-04-09 And note, dev-python/docutils-0.21.2 is stable now. I think something like #930076#c9 is necessary here. I'm not using this package and found this problem with grep. Please, check.
