The code is correct.  The object in question is defined in rfc1035_res.c, 
which is included in the ar library that's being linked against.

I recall that this is a known, longstanding issue with OSX's linker which 
fails to resolve non-functional external objects.  You might want to 
consider looking into the BSD ports to see what they do to work around it. 
OSX's and BSD's linker share a common history, and a common set of bugs.

mvwaddstr should be declared in /usr/include/curses.h

Having said that: Cone checks if your curses supports wide characters; if so 
it reads /usr/include/ncursesw/curses.h, if that's the case.  This 
particular code fragment uses the wide character curses code; you'll need to 
check what's declared in your ncursesw/curses.h

-C option to the configure script enables some caching.

Cone does not use the aspell binary, it links against the aspell library 
directly.  You need to have libaspell.so installed, as well as aspell's 
header files in /usr/include/aspell
