Yeah, try this:
ln -s /usr/lib/libncurses.so /usr/lib/libncurses.so.4
I don't have a Mandrake 9.2 box, so I'm just guessing, but that will work on Red Hat 9. At any rate, if it doesn't, then do this:
ls -l /usr/lib/libncurses*
and see what that most recent library is (the one that isn't a link to something else, probably libncurses.so.5.3), and make a link to it called libncurses.so.4 like this:
ln -s /usr/lib/libncurses.so.5.3 /usr/lib/libncurses.so.4
EDIT: It looks like Mandrake has them under /lib, so you'd want to use /lib instead of /usr/lib in the examples.
