(Unsetenv LD_LIBRARY_PATH before linking)

The solaris FAQ says:

6.11) 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 the
    previous question, you will have no such problem.
