Comment # 8 on bug 940207 from Dr. Werner Fink

(In reply to Jiri Slaby from comment #6)

The configure as well as the Makefile are broken ... with

 %build
 NCURSES_CFLAGS="$(ncursesw6-config --cflags)"
 NCURSES_LDFLAGS="$(ncursesw6-config --libs) -lpanelw"
 export NCURSES_CFLAGS NCURSES_LDFLAGS
 %configure
 make %{?_smp_mflags};

it works flawless
