very likely there is an already-installed copy of ncurses which is 
conflicting with this.  I don't recall if the rpath (configure) option
would help here (it has drawbacks), but you may get better results by
setting LD_LIBRARY_PATH to your build-tree's lib-directory, as the
misc/shlib script would do, e.g.,

        sh misc/shlib make
