It does find it, it just fails to link a program with it. That is because
readline requires libncurses (or equivalent). On my system I can: 

bash-2.04$ ldd  /usr/lib/libreadline.so 
        libncurses.so.5 => /lib/libncurses.so.5 (0x40029000)
        libc.so.6 => /lib/libc.so.6 (0x40067000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

Showing it is correctly configured. It seems it isn't on yours. I assume that
is a bug a bug in the readline install... I do not know how to add the
dependensy.

If you just want to compile freeciv with it you can edit configure.in to skip
the readline test and add -lncurses to the server libs.
