likely that FreeBSD’s python39 does not make a python3 symlink under the sys bin automatically.

Suspicion confirmed: https://forums.freebsd.org/threads/which-python-calls-to-python3-dead-end.74981/

Not sure what to do as I am not so sure about creating a system wide symbolic link for in a conf package. Creating a switch specific link is probably a way to go, but I’ll opt to tentatively mark 3.9.0.0 as unavailable for FreeBSD as 3.1.0.0 works.

[haochenx]

Indeed, I think we should probably reorganize versions to have a conf-python3.1 as the only version to be on par with other conf packages

Suggested change

	["dev-lang/python:3.6"] {os-distribution = "gentoo"}
	["dev-lang/python:3.9"] {os-distribution = "gentoo"}

[mseri]

I won't do this since I don't know if it works

Thanks for the help and the patience @haochenx
