Reproducible: Always

Steps to Reproduce:
1. Move the /var/db/pkg/ tree on separate partition
2. Run 'equery list foo' under unprivileged account

dev-portage:

The traceback is coming from portage. Do I need to do something different in
gentoolkit or is this a bug that you need to fix?

The PermissionDenied error needs to be handled by gentoolkit. For compatibility
with portage-2.2 I suggest something like this:

try:
 import portage.exception as portage_exception
except ImportError:
 import portage_exception

try:
 # do stuff with portage api
except portage_exception.PermissionDenied, e:
 # handle error

Zac: Thanks! I stole the code from emerge to fix.
