The new graphics ports and pkg-base

[Grzegorz Junka]

I am trying to understand the impact of distributing ports with sources 
on building and packaging base with pkg.

If I understand correctly, some ports, when installed with pkg, extract 
sources, which then supposed to be compiled with the kernel.

For instance, drm-current-kmod extracts lots of files into 
/usr/local/sys/modules/

Would that mean those ports have to be installed on the host that is 
used to build the kernel and world, which are then packaged with 'make 
packages' into pkg-base?
