It an option to ./configure (see ./configure --help for all the
options).  However ...

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.

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

Hopefully, such drastic measures are not required.  I think the conflict
between the various curses libraries is likely the problem.  That is,
the Apple curses probably declares the _gtty and _stty functions/macros,
but there is nothing in libncurses with those symbols.
