Again: I think the bug is that curses is not listed as a dynamic load 
dependesy. The nicest solution would still be to make people install readline 
correctly, possibly by giving fixes to the upstream maintainers.

If you just want to run it locally then run the server link command manually 
with an added -lcurses. Or append -lncurses to SERVER_LIBS in configure.in.

Possibly we ("we" as in "you", it works on debian :)) could add a lot of 
stuff to the freeciv configure.in to determine which curses lib to link with, 
but the correct place to fix this really is with the people distributing 
readline! (So it seems to me; somebody say if I am wrong)

Finally, all this configuration stuff is something I really don't have much 
knowledge about, so someone else go fix it :).
I admit I would be more motivated to fix it if it affected me, but that is 
life :). (witness how long it took from the point I apt-get installed the 
somewhat incompatible readline 4.2 to freeciv became readline 4.2 compatible)
