I put a color version of ls in
ftp://ftp.freebsd.org/pub/FreeBSD/incoming/colorls.tar.gz (source)
ftp://ftp.freebsd.org/pub/FreeBSD/incoming/colorls.tgz (package)
Note that the regular xterm doesn't understand ANSI color sequences.
I use color_xterm and kterm (both available from ports).
Diffs from the stock version are included below for your amusement.
