In my opinion, nobody should use mdf for anything, certainly not anything
structural. By "door frame" do you mean "door jamb"? If so, yes, rip pine
to the correct width, or, you could maybe find a jamb kit which was too wide
and rip it down.

I am installing door frames on a supporting wall, and thus regular sized
frame kits don't fit. I was looking at ripping either pine or MDF to the
right width. The door frame will be painted white. I'm a bit concerned
that MDF might be to soft -- is that true, or is it sufficient?
