Why do I get undefined symbols when linking with curses/termcap?

It is easy to mixup the BSD libcurses and the SVR4 libcurses.
One lives in /usr/ucblib, the other in /usr/ccs/lib, when
you've installed SUNWarc. Note that when you specify:

-L/usr/ucblib -lucb -L/usr/ccs/lib -lcurses

you will pick the ucb version of libcurses, not the SVR4
version. If you always put libucb last, as recommended in 6.18,
you will have no such problem.
