    - Put "set -x" at the top of the configure script, then post the last
      thirty or so lines of the output once it gets stuck.

So it's not doing a whole lot, but doing it slowly: there are delays of
perhaps 5-10 seconds between a number of those lines.

    - Look in all the tmp directories your system has (/tmp, /usr/tmp,
      /var/tmp, etc) and see if there's a large number of scratch files
      created by the configure script.

Yes, 605 of them.
