After doing this 50 times, it got boring and I gave up.

Last time I debugged XFree86, I didn't have this problem(or maybe once
or twice).

How many times should I have to endure this requester under normal
circumstances?

Perhaps something is actually wrong?

To even debug XFree86 I have to fix a long outstanding complicated
