This is why we bootstrap python-2.6 on all non-Linux platforms.  Check
the Solaris bootstrap guide for a much less-optimistic bootstrap
procedure.

Prefix support is defined in PMS as EAPI-3.  The "reference"
implementation, is the Prefix portage "prefix" branch [1], which does
much more than is documented in PMS, to 1) ease transition for Prefix
users (it e.g. defines EPREFIX and friends for *all* EAPIs) and 2) check
all kinds of conditions that only make sense in an offset environment.

You probably want to look at prefix-launcher (I don't know the
intrinsics of this thing), and you might want to check what the
gentoo/openbsd team is doing currently to automate their OpenBSD
bootstrap.
