It was almost certainly what I said above. Too bad you weren't able
to follow through with it.
I was running the make depend for over 1 hour and it showed no end in
sight. I figured to run that to the finish and the full make it might
have taken all day so I really had no choice :)
I will test this and see if it fixes the problem and confirm if this
is the culprit (or not).
I am surprised to hear this is all a function of the Quota problem
you mention. I suppose nobody is using this anymore or is there a
better system being used?
