I'm not sure if PTGui allows you to redistort an image based on your lens solution, but if it does, you can read in a 32-bit normalized UV ramp (0 to 1 in X and 0 to 1 in Y) that is the size of your undistorted plate and use the resulting distorted UV image to feed into nuke's lens distort node or an STMap. I've used this technique coming from boujou and it's spot on.
