I'm nut sure you can put that sort of thing in package.env, I thought it
was only for settings variables, like make.conf but per-package. You can
add function calls in /etc/portage/env/cat/pkg, for example I have
used this for a couple of packages that didn't support epatch_user

post_src_unpack() {
        cd "${S}"
        epatch_user
}

AFAIK you can do this for any of the standard ebuild functions listed in
man 5 ebuild.
