What you're after is known as "Prefix/Stack", where you have some "base"
Prefix, which's portage does manage packages in another - stacked - Prefix.
While this does work already with "Prefix/Guest" as base Prefix, there is no
technical reason to not work with "Prefix/Standalone" or even "Gentoo Linux"
as the base Prefix. The only problem maybe is that "Prefix/Guest" does use
a portage version with additional patches.
But still, you can get an idea about how this works, using "Prefix/Guest":
$ docker run -t -i gentooprefix/prefix-guest-64bit-fedora -c /bin/bash
At the docker prompt:
Enter the Guest Prefix preinstalled to /tmp/gentoo:
$ /tmp/gentoo/startprefix
Set up your stacked Prefix:
$ prefix-stack-setup --eprefix=$HOME/stack --profile=/tmp/gentoo/etc/portage/make.profile
Note that "~/stack" will not work here, bash refuses to resolve '~' after '='.
Leave the Guest Prefix:
$ exit
Enter your just created stacked Prefix:
$ ~/stack/startprefix
Emerge your package, for example:
$ emerge sys-libs/zlib
Have fun!
HTH,
