Hi,

Thanks for the tip w.r.t. getting clang out of the buildworld.

Maybe this can be written down on some Wikipage . freebsd . org ?

The title could be "Who are my dependencies when changing code?", and it 
should answer the following questions like some kind of flow graph:

- Shortcuts for kernel builds.
- Shortcuts for user-space builds.
- Shortcuts for ports interactions.

- When do I only need to build a kernel module.
- When do I only need to build a single utility.
- When do I do a full kernel build.
- When do I do a full user-space build.
- When do I do a universe build.
- When do I ask ports guys for help.
