make menuconfig fails while working on busybox only

I was following the guide here and when I tried running make menuconfig it said

Unable to find the ncurses libraries or the required header files.
'make menuconfig' requires the ncurses libraries.
Install ncurses (ncurses-devel) and try again

ncurses-devel doesn't exist on the AUR though. I tried reinstalling ncurses but it still wouldn't work. It does work when working on the Linux kernel. Also I do want to compile a 64 bit version so I don't think that I would need a 32 bit version of ncurses. Edit: I have given up on this I don't really need to do it anyways.
