Here is the output:

maude:/etc/ldap# ldd /usr/sbin/afacli
         linux-gate.so.1 =>  (0xffffe000)
         libncurses.so.5 => not found
         libpthread.so.0 => /lib32/libpthread.so.0 (0xf7f7f000)
         libstdc++-libc6.2-2.so.3 => not found
         libm.so.6 => /lib32/libm.so.6 (0xf7f58000)
         libc.so.6 => /lib32/libc.so.6 (0xf7e17000)
         /lib/ld-linux.so.2 (0xf7f9d000)

Not sure what the libstdc++-libc6.2-2.so.3 is, but it really does appear 
to be missing, The closest things to it were /usr/lib/libstdc++.so.6 and 
/usr/lib/libstdc++.so.6.0.9. As I mentioned before, libncurses.so.5 is 
in /lib. Does the last line mean that it is finding some stuff in /lib?
