(1) Clarify the use of ${MOTIFLIB} by giving examples on what to

substitute.

(2) Bring the *_DEPENDS section up to the current state.  Explain that
    the pathname in the "path:dir" pair can be a full pathname if you
    want a port to depend on something that isn't executable or an
    executable that's not expected to be in the user's search path
    (like /usr/local/libexec).  Also, change the LIB_DEPENDS example
    to use jpeg, tcl-7.3's appropriateness as an example is quite
    outdated at this point. ;)
