Lesstif doesn't require this (there is no libXp :).  It sounds like a
compile switch for make is needed.  I'm unsure which way to jump with
this in terms of the default.  Maybe as there are a number of commercial
Motif implementations the correct switch is for Lesstif.  That is, make
-lXp the default, to be ignored if you do "make LESSTIF=1 world" maybe.
Thoughts?

I have tried Metalworks successfully previously, but not with the current
set of patches.

Definitely.
