Description Sergei Trofimovich (RETIRED) gentoo-dev 2021-04-09 09:57:20 UTC 
In https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e64c97da5d53b1205efeba729fc9bd10546f25e8 package discovers python3 as:

    import('python').find_installation('python3')

I did not find any generic command-line options I could override 'python3' resolution and ended up doing a sed hack:

	sed "s/py3_exe = import('python').find_installation('python3')/py3_exe = import('python').find_installation('${EPYTHON}')/" \
		-i subprojects/sdb/meson.build || die

I suspect that injecting
    [binaries]
        python3 = ${EPYTHON}
would make it Just Work.

Should meson.eclass provide a mechanism for ebuilds to do it? Or maybe there already is a way to do it already?
