You have to install LessTif (or Motif) before installing
DDD; c.f. http://www.gnu.org/software/ddd/#Building

When I installed it, the library was put in /usr/local/lib:

    $ ls /usr/local/lib/libXm*
    libXm.la@  libXm.so@  libXm.so.2@  libXm.so.2.0.0@

Also, after you install a new library (like LessTif), you
have to (or at least I generally do) reload the run-time
library table (or whatever it does):

    # /sbin/ldconfig

Probably the LessTif install instructions (or `make install`)
will mention that (if you forget, ddd might complain that it
can't find the shared library or something).
