Here is a script I use to check directory usage:

------------------------ Start of script ----------------------------
#!
# Checks the space used by a directory
# Written by D'Arcy J.M. Cain

# default to current directory else from command line
if [ "$1" = "" ]
then
	directory=`pwd`
else
	directory=$1
	shift
fi

while true
do
	if [ "$directory" = "" ]
	then
		exit 0
	fi

	echo "$directory \c"
	ls -iRl $directory | awk '{ if (NF > 5) print $0 }' | sort | awk '{
		if ($1 != last_inode) size = size + $6
		last_inode = $1
		}
		END { print size }'

	if [ "$1" = "" ]
	then
		exit 0
	fi

	shift
	directory=$1
done
---------------------- End of script ----------------------

The difference is that subdirectories are included and links are only
counted once.  Also there is a little user friendly wrapping.  HTH.
