When I did that, it complained about the syntax.
Apparently, from what I read through google-searches, /etc/portage/env/... is 
handled by Python. And that doesn't, obviously, understand bash-syntax.

/etc/portage/bashrc is handled by Bash, which makes this possible.

The "pkg_postinst()" is for either ebuilds, or I am doing something wrong...

I am using the latest stable portage.
