Yes, xterm needs ncurses. I have the following patch in one of my
branch since July 2010, but never had the time to finalize it. I think
it should fix your problem:

Hum, which driver failed exactly ? Because for example
xdriver_xf86-input-evdev already has the dependency on
xserver_xorg-server. And from a quick look, it seems that all other
input drivers also have xserver_xorg-server in their dependencies.
Could you bit a more specific about the failure (i.e give us
the .config + build log) ?

Thanks !
