Oops, make that:

    `(#:configure-flags
      ,(cons*
        'quasiquote
        `(("--with-shared" "--without-debug" "--enable-widec"

           ;; By default headers land in an `ncursesw' subdir, which is not
           ;; what users expect.
           ,(list 'unquote '(string-append "--includedir=" (assoc-ref %outputs 
"out")
                                           "/include"))
           "--enable-overwrite"      ;really honor --includedir

           ;; Make sure programs like 'tic', 'reset', and 'clear' have a
           ;; correct RUNPATH.
           ,(list 'unquote '(string-append "LDFLAGS=-Wl,-rpath=" (assoc-ref 
%outputs "out")
                                           "/lib"))
           ;; MinGW: Use term-driver created for the MinGW port, libtool.
           ,@(if (target-mingw?) '("--enable-term-driver" "--with-libtool") 
'()))))


Greetings,
Jan
