The startup scripts support pf, but do not require it.

It is a part of the base system.  It is always present just like ipfw,
but its use is not required.

You are fine the way you are.  I recommend letting mergemaster update
the default pf startup files, so that it won't ask about them next
time, but it doesn't really matter if you're not using pf.
