It says something about an old/bad ncurses library/header but I have the latest lib/ncurses-1.9.9e.bin.tar.gz from the Linux/m68k mirror!
Get and install the current version of the ncurses development package (libncurses4-dev, if you're using Debian 2.1). If you're using apt, use the following command:
apt-get -y install libncurses4-dev
You should then be able to type "make menuconfig" in your Linux source tree.
