I'm afraid that I giggled a bit while I read this. Surely you know the
difference between udev and libudev, and after a brief inspection of
the code, original and newly added, you can see that it differs
significantly. Additionally the newly added LIBUDEV_{CFLAGS,LIBS}
should be a nice give-away :-)

That aside, I'll send a revert in a second as mentioned previously.

Thanks
