As far as I understand shared libraries, it's not (usually :) a matter
of where the _package_ expects the library to be - the program (frotz
in this case) tries to link to a certain shared library
libncurses.so.3.0.

If the library cannot be found in any of the directories listed in
/etc/ld.so.conf *and* is not in any of the directories in
$LD_LIBRARY_PATH then the system will chuck an error and program will
not run.

Check that that directory is listed in /etc/ld.so.conf. If it is not,
add it, then run (as root) "ldconfig -v". You should then see the
appropriate library scroll past (along with all the other system shared
libraries)

Try both.

(no, really, I'm serious :)
