i fixed this one by changing the path of the curses.h check in fairsoft/tools/root/configure from
if test ! "x$enable_editline" = "xno" ; then
check_header "ncurses.h curses.h" "$cursesincdir" \
/usr/include/ncurses /usr/local/include/ncurses \
/usr/include/curses /usr/local/include/curses \
/usr/include /usr/local/include
cursesincdir=$found_dir
curseshdr=$found_hdr
to
if test ! "x$enable_editline" = "xno" ; then
check_header "ncurses.h curses.h" "$cursesincdir" \
/usr/include/ncurses /usr/local/include/ncurses \
/usr/include /usr/include/curses /usr/local/include/curses \
/usr/local/include
cursesincdir=$found_dir
curseshdr=$found_hdr
i guess else he does not find the curses-devel file or so .)
