A bit of digging in the archives suggests that my hindbrain remembered this:
http://www.postgresql.org/message-id/flat/4F5A8404.8020708@dunslane.net

The specifics probably don't apply to anole, but the conclusion that
inconsistent openssl header and library files triggered the bug might.

Maybe it'd be worth trying to see if we could detect such inconsistencies
during configure?
