Rick,

I have reviewed the configure logic and it still seems reasonably
sound. One thing I notice is that if *none* of the probes work the
build tree targetted configuration will get used instead of the more
reasonable install tree configuration.  But still, if this case kicks
in it means none of the link probes worked.

You are welcome to reopen the bug report, and document there why you think
it is broken.  But you will need to be quite specific, and you likely ought
to carefully review your config.log file for what happened in the proj
related probes.
