It would seem that your curses library is a different version that the curses headers you have installed, and thus doesn't
have acs_map (you can check by running grep on the curses libraries - probably in /usr/lib).  The library is there and linkable,
otherwise the configure test wouldn't have passed.
I suggest you check the dates of the files and the packages you have installed from your distro.
