>Description:
        emulators/qemu work fine, but nobody can run it in a machine that that
        has no X11 libraries (even with the -no-graphic runtime option).  The
        --disable-sdl option is enough to prevent it from linking against X11
        libraries.

        I've tested it in NetBSD 5.0 with py-anita and it runs really fine.
>How-To-Repeat:
        Install emulators/qemu in a machine without X11 (you can make package
        in another one and bring it where there is no X11) and try to run it.
>Fix:
        Using the options framework, the following patches give the user
        the choice on using sdl or not:
