Hello,
my first question:
In ptxdist git repo, I can see in rules/udev.make that you use udev version 182, but that version requires at least libkmod > 5, but I don't see that you use kmod anywhere. How does your udev builds without kmod?
second question: 
I am trying to get udev 182 to build, already did it outside of ptxdist, and since you don't have kmod, could you please me suggestions/advice/help on how to properly write rules/kmod.in and rules/kmod.make for the latest version which is 25??
