 Recent versions of Homebrew (a package system for OS X) creates a
 link from "python3" to specific "python3.x", but not from
 "python3-config" to specific "python3.x-config".  The current BIND
 10's configure script first finds "python3", and subsequently searches
 for "python3-config", which fails.

 Maybe it's a bug of Homebrew, but at least we can work this around by
 changing the search order of the main Python executable (see attached
 diff).

 If this doesn't do harm for other OSes or other OS X package systems
 I propose applying this patch.
