I am currently running the ter patch (w/o the IRQ patch) to get a comparison
of the two, but with it ppsctl works fine, no error message.

This is both ppsctl compiled some time ago, and one compiled just now.
I will want to wait a wile before going back to ter+IRQ to test there.

So for me, works fine, at least with ter only.
