That could work, but then I'm back to building from source.  (macports uses binaries for most stuff, btw.)

I'm happy to investigate further _if_ a homebrew dev says that they officially support installing this way.  There's a similar way

to change the deployment target for macports.  But one of the devs told me that kind of compatibility isn't a design goal and

they don't support doing that.
