Readline depends on libncurses. Try doing

bash-2.04$ ldd /usr/lib/libreadline.so 
        libncurses.so.5 => /lib/libncurses.so.5 (0x40030000)
        libc.so.6 => /lib/libc.so.6 (0x4006e000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

If ldd doesn't show libreadline.so to require libncurses, the test linking
./configure does will fail. It is a bug in RH7 I guess.
I you really want to compile with readline support then edit configure.in to
not test for readline and add -lncurses to the server link libs.
