I'm sorry but do you even use Gentoo, these days? Like the real Gentoo,
not just some little part you've installed years ago and then modified
only Java stuff in it?

Perl does not use TARGETS. It uses subslots, after it used horrible
custom rebuild tool. The latter brought many bug reports of users being
hit by random breakage on upgrades, the former just brings *tons* of
problems with Portage not being able to deal with Perl upgrades.

PHP *uses* PHP_TARGETS.

Python used not to use TARGETS. The results were random
incompatibilities between packages that were hard to track and random
breakage. Now we're past that. But I can understand it's not the Gentoo
of your times where user was expected to watch his every step to have
his system boot again.
