Make menuconfig dependency not met

[Patrick <patrick@kirks.net>]

Can anyone drop me a line to say what I've forgotten to install?

enterprise:/usr/src/linux# make menuconfig
rm -f include/asm
( cd include ; ln -sf asm-i386 asm)
make -C scripts/lxdialog all
make[1]: Entering directory `/usr/src/linux/scripts/lxdialog'
find: /usr/local/lib/: No such file or directory
gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -DLOCALE  -DCURSES_LOC="<
curses.h>"   -c -o lxdialog.o lxdialog.c
In file included from lxdialog.c:22:
dialog.h:29: curses.h: No such file or directory
make[1]: *** [lxdialog.o] Error 1
make[1]: Leaving directory `/usr/src/linux/scripts/lxdialog'
make: *** [menuconfig] Error 2

Thanks.
