Right. I always forget which version got libc++ by default (I skipped 10.7 and 10.8 myself so never had to deal with the situation).

Agreed. Sadly it isn't always trivial to figure out which code really needs it, other than waiting for errors like the one I received.

How do the bots decide not to build ports for which licensing makes binary redistribution "impossible"? Is that also handled by raising an error?

Something that doesn't involve raising an error you mean?
Although, the easiest way to implement this would probably be through a predefined error return code which could then be handled differently on user systems and on the build bots.
