Mono -- does it really need X11?

Mono's library dependencies:
Library Dependencies: gettext, glib2, libiconv, zlib, libgdiplus, xorg-libX11

And, Gtk2 also has:
Library Dependencies: atk, pango, gdk-pixbuf2, gobject-introspection, xorg-libXi, xorg-libXrandr,
                      xorg-libXcursor, xorg-libXinerama, xorg-libXdamage, xorg-libXcomposite, xorg-libXfixes

So, call this ignorant user error -- how would I make this work without X?

(Turns out it is low priority -- the program that I wanted to install (a GIT interface) turns out to now be out of date, abandoned, and replaced by a windows-specific newer program).
