While trying to emerge @system for a new crossdev environment, I found that dev-lang/python-3.11 requires a new flag in the configure stage `--with-build-python`, and a version of python on the host that matches the same minor version. I was able to successfully emerge dev-lang/python-3.10.4_p1, so I'm assuming this is a change for >=3.11 There's some discussion of this flag on upstream's mailing list late last year: https://mail.python.org/pipermail/python-bugs-list/2021-December.txt

I suppose the EAPI 8 way of doing this would be to build the host executable in a temporary directory first, and then pass it to the actual build.
That probably won't be pretty. It's times like this that I wish we'd kept the (admittedly badly-named) targetroot USE flag from EAPI 5-hdepend.
Well, or BDEPEND on it + checking BROOT to see if we're build cross?
(In reply to Michał Górny from comment #6) > Well, or BDEPEND on it + checking BROOT to see if we're build cross? Oh wait, wrong. BDEPEND would break regular installs.
Yeah, that was the point of the flag. The flag didn't check for cross, just for ROOT!=/ or something like that, although technically you should probably just base it around SYSROOT!=/.
came here to report this. for now I'm using EXTRA_ECONF but hope you guys will come up with elegant solution soon
