From c0724b8e7aefd9ced1740a970941928f5b168b2b Mon Sep 17 00:00:00 2001
From: Jameson Graef Rollins <jrollins@finestructure.net>
Date: Sun, 5 Apr 2009 15:05:36 -0700
Subject: some small compatibility changes: - fix file_hash function to use md5
 or md5sum, for Darwin compatibility - use build-in 'type' instead of 'which',
 which for some reason doesn't behave on Darwin - clean up some redirection
 calls.
