Great, the change looks very simple:

From 690c42cd1ba00ba9b979cf9665dba75aa76d8c98 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Remove PKGDIR munging

This isn't needed anymore.

Thanks, but this is not quite what I want. This depends on the user actually passing
-K to emerge. I realize I want something like the different -bin ebuilds
in portage such as openoffice-bin or firefox-bin.
Any pointers on how to create a -bin ebuild from the binary pkgs I
get form crossdev ... -portage -b ?
