A difference between Zack's good output and your bad output is that 
Zack's build did not rebuild configure (it's two seconds older than 
autom4te.cache/requests) but yours did.

I'm not sure exactly what's going wrong. Part of the problem is that I 
suspects later actions by the bad 'configure' overwrote some timestamps 
that were treated incorrectly.

In reading the code it's clear that it's confused about timestamps in 
this area as it is using the maximum of two timestamps when it should be 
using the minimum. I installed the attached patch, which fixes that bug. 
However, I don't know whether that will address the problem you observed.
