From d0795c1638cb1f7837fad6395251deef1dbf1757 Mon Sep 17 00:00:00 2001

Subject: Check if ebuild path is in vdb and check that vdb finds it okay
 rather than always assuming "porttree". If PORTDIR_OVERLAY needs to be
 adjusted, recheck to make sure the ebuild is found correctly. Pass which tree
 should be used to doebuild so that aux_get() are performed on the correct
 tree.
