libtool 1.3.4/5 seems to be on the first 3 systems I've checked.

Since we don't run libtool interactively we just put this to the
LIBADD flags accordingly!? However the example is dones using an installed lib
being libmath.*.
As indicated my version
libDt_la_LIBADD = -L../Xm-2.1/.libs -lXm
seems to work, but I just can't see this documented here.

See the discussion when I added -lm to the libXm.
