I know you love to keep saying this. And I have no objection to moving toward defaulting to libc++ on 10.6-10.8, as has been discussed in other threads. But Rainer's reply here was in response to my pointing out the https tls problem, which does not go away even when we move those systems to libc++.

Yes, I know you like to build your legacy MacPorts installs with a different copy of curl. And yes, we have a ticket tracking that issue as well.
