Fred Alger 834f6a216d Make shell outs to md5sum work on FreeBSD and OS X
Tested with OS X local connection and Linux remote. The paths to the
md5sum and md5 commands are hardcoded to the most common location. This
will definitely fail if the commands are elsewhere, or if the md5
command doesn't support the -q 'quiet' option.
