 When building GHC, the configure script will not check for ncurses, even
 though it is required for the build of terminfo. Without it installed, the
 build fails mid-way in with:

 {{{
 checking for stdint.h... yes
 checking for unistd.h... yes
 checking ncurses.h usability... no
 checking ncurses.h presence... no
 checking for ncurses.h... no
 checking curses.h usability... no
 checking curses.h presence... no
 checking for curses.h... no
 configure: error: in `/home/linaro/code/ghc/libraries/terminfo':
 configure: error: curses headers could not be found, so this package
 cannot be built
 See `config.log' for more details
 }}}

 I think that configure should check for ncurses immediately so you don't
 accidentally lack a dependency. It's just annoying.
