Comment(by judahj):

 It seems that ncurses was changed recently (?) to allow splitting off the
 terminfo-specific functionality into a separate library.  The fix should
 be pretty simple; just edit configure.ac and change

 AC_CHECK_LIB(ncursesw, setupterm, HaveLibCurses=YES; LibCurses=ncursesw,
   [AC_CHECK_LIB(ncurses, setupterm, HaveLibCurses=YES; LibCurses=ncurses,
     [AC_CHECK_LIB(curses, setupterm, HaveLibCurses=YES; LibCurses=curses,
       HaveLibCurses=NO; LibCurses=not-installed)])])

 adding an extra line to try tinfo first, and otherwise fall back to the
 above curses variants.

 Unfortunately, I don't have a system with libtinfo to test this on.  Can
 someone please confirm whether that fixes the problem?
