What about something along the lines of 

# Get the current date but leave minutes hanging
DATE=`date +"%Y%m%d%H %M"`
# prep DATESTR with the YYYYmmddHH
DATESTR=`echo $DATE | awk '{print $1}'`
# Extract the minutes
MM=`echo $DATE | awk '{print $2}'`
# Make it one minute in the past
let MM--
# Append the minutes back to the datestring
DATESTR="${DATESTR}${MM}"
# touch .stamp and all directories in .build/src with that time.
touch -t ${DATESTR} .stamp *


Now, after we extract the next package, we look at the directory to see
what has changed:

# Extract the time stamp of the .stamp file
STAMPTIME=`ls -la .stamp | awk '{print $6" "$7}'`
# Get the listing of all files that are NOT that stamp file
# This _SHOULD_ be any directory that was added/modified.
DIRS2UPDATE=`ls -l | grep -v "$STAMPTIME" | awk '{print $8}'`

Yes, I understand I'm a sick puppy, but hey, if it would keep from
having to
re-chmod the WHOLE directory EVERY time, it would be a good thing.

You don't have to add it if you think I'm smokin' something.  It is just
a suggestion -- and I know how to make a patch file for my personal use
;).
