That's correct, I'm aware. But I also saw in this list (and correct me 
if I'm wrong) the mention of work being done to remove the CLT 
requirement in future MacPorts versions, and making sure that the SDK 
used corresponds to the version you're running.

This was mentioned in the recent mail that I mentioned seeing recently, 
but couldn't find in the archives. If you're the author of that mail and 
you're reading this, could you please chime in? Thanks.
