From 6f870968edd09479410f3a6a52bb0be75e327366 Mon Sep 17 00:00:00 2001
From: Aaron Griffin <aaron@archlinux.org>
Date: Fri, 9 Mar 2007 05:33:06 +0000
Subject: * Two fixes when running under a new root (-r|--root)     - Check
 EACCES in can_remove_file, to verify - we're only checking for a      
 read-only FS here... if write permissions fail, we can still remove it     -
 Switched the message when creating DB directories from an error to a debug   
    message * Fix the dep tests once and for all (it wasn't working for
 provides=()   packages)
