Yes, this is most likely the problem. You might temporarily move
libncurses includes (*.h files) and libs (libncurses.a, libncurses.so)
to a directory where the compile won't find them. It may be the curses
library supplied by Apple is sufficient to do the job.

Thanks Eric, I'll try that now.

The option is -I/path/to/includes for header files. The -L/path/to/libs
is only used by the linker (ld) for libraries.

Mmm, well the linker is what is reporting the error. Here is an example copied from the shell (running gmake5):

#################################################################
/usr/src/grass/src/display/d.colors
  make -f OBJ.powerpc-apple-darwin1.2/make.rules

cc -L/usr/local/lib/ -o /usr/local/grass5/etc/bin/main/cmd/d.colors OBJ.powerpc-apple-darwin1.2/curses.o OBJ.powerpc-apple-darwin1.2/sigint.o OBJ.powerpc-apple-darwin1.2/set_sigs.o OBJ.powerpc-apple-darwin1.2/get_info.o OBJ.powerpc-apple-darwin1.2/interact.o OBJ.powerpc-apple-darwin1.2/tbl_toggle.o OBJ.powerpc-apple-darwin1.2/tty.o OBJ.powerpc-apple-darwin1.2/main.o /usr/src/grass/src/libes/LIB.powerpc-apple-darwin1.2/libdisplay.a /usr/src/grass/src/libes/LIB.powerpc-apple-darwin1.2/libraster.a /usr/src/grass/src/libes/LIB.powerpc-apple-darwin1.2/libgis.a
/usr/bin/ld: Undefined symbols:
_wborder
_gtty
_stty

So wouldn't I use -L/lib/path??

That usage would be correct (not -L/path/to/headers !).

Well, I can't say for sure where that stuff is coming from on your
system. But, I would think the symbols are actually declared in the
header files (which are processed prior to compilation to object files).
However, later the linker tries to preferentially link to a library that
has *some* but not *all* of the symbols defined by the headers and hence
the mismatch. Try grep'ing for those symbols in /usr/include and see
which files they turn up in (possibly term.h or termios.h).

Perhaps someone with more BSD experience can be of more help.
