If you found our tutorial to be non-functional on BSD for whatever reason, the thing to do would be to tell us the problem, and how you fixed it, so we could add the corresponding line ("on BSD, you first have to...") to our tutorial. Better yet, since our tutorial is located in the Wiki, you could make the necessary edits yourself.
Spawning information like that is not so smart, because any changes we make to our tutorial here (like, adding the things necessary to compile GCC 5.0 or somesuch) won't be added to your BSD tutorial. That's why a link is the superior solution here.
As with databases. Redundancy is evil.
