Okay, I'll do the that step for you. This is not my field (no pun intended) but I think it might make sense. The relevant vertex is the bottom one in that pic. Since it's analogous to the QED vertex

I assume you can compute polarization contributions of ghosts analogous to

notice how you put two of the g·f·\Gamma vertices from the pic together, which would be second order in g.
