This will trigger unwanted filename expansion. For example,
PATH='/*/bin'
will trigger '/usr/bin' rather than '/*/bin' :P.
Good catch, thanks. This version uses 'set -f' to fix that:

Subject: [PATCH] bin/ebuild-helpers/portageq: fix bug #524964
Since commit 0cc4c1ac21a2ea94cfb1f6ff4b461a9e349d47df,
$PORTAGE_BIN_PATH/portageq no longer exists, which breaks
bin/ebuild-helpers/portageq. Note that has_version and best_version
rely on bin/ebuild-helpers/portageq if IPC is disabled, so breakage
extends beyond ebuilds that call portageq illegally. Since
$PORTAGE_BIN_PATH no longer works, use PATH to locate the real
portageq python script.
Fixes: 0cc4c1ac21a2 (Install Portage using setup.py)
