Created attachment 543190 [details, diff] patch for terminus-font-4.46.ebuild media-fonts/terminus-font-4.46 requires python3 to build, but the ebuild does not have the proper dependencies and emerging fails with "No supported Python implementation installed." instead of pulling such a python implementation. Adding ${PYTHON_DEPS} to DEPEND (and removing ${PYTHON_DEPEND}) fixes this, patch attached.
Same issue with 4.47 It was also necessary to change PYTHON_COMPAT=( python3_{4,5,6,7} ) into PYTHON_COMPAT=( python3_{5,6,7} )
This has been fixed by mgorny in commit f3c04f38e8120d280d4e1fa3596314b532a649ca for versions 4.46, 4.47 and 4.48.
