CRUX

I run qemu on a headless host that doesn't have the xorg repo. With some minor package tweaks qemu builds and runs well. Some of these might be worth considering:

1) xorg-libpixman doesn't need any xorg deps. I suggest moving it to opt, unless there's a reason it needs to be in the xorg repo. Right now I just fetch a copy of the port to avoid syncing the whole xorg repo.

2) Building libxkbcommon requires: -D enable-x11=false. There's actually already a check for wayland, I suggest adding a similar one for xorg-server, which would be helpful anyway for people migrating to a pure wayland setup in the future.

This is what I add: prt-get isinst xorg-server || PKGMK_XKBCOMMON+=' -D enable-x11=false'

3) The qemu package requires a dependency on libxml2. It was probably omited since it gets pulled in from it's current dependency on something from xorg.

4) In order to make it headless I also add: --disable-sdl --disable-opengl. I'm not sure how to make that flexible. Maybe have a qemu-headless package?

None of these issues are a big deal, but I think 1 2 and 3 have no downsides and are easy changes.
