Several options:

1. Recompile the curses library either as a shared library or with
-fPIC, so that shared libraries can be linked against it.

2. Remove the line:

	EXTRA_LIBS=$(CURSES)

from lib/vask/Makefile, and change the line:

	VASKLIB       = -l$(VASK_LIBNAME)
to:
	VASKLIB       = -l$(VASK_LIBNAME) $(CURSES)

in include/Make/Grass.make and/or include/Make/Grass.make.in.

3. If Solaris provides a shared [n]curses library in /usr/lib, create
a symlink named libncurses.so in e.g. /usr/local/lib.

The configure script prefers -lncurses to -lcurses, so if you have a
shared libcurses and a static libncurses, it will chose the latter,
even though the former is preferable. OTOH, if you have both shared
and static versions with the same name in the same directory, the
shared version will normally be preferred.
