MacPorts and clang

[Jack Howarth]

  Are there any plans to attempt to move MacPorts towards
building with clang once Xcode 4 is released? Considering that
we have so many packages supporting gcc4x variants to build with
FSF gcc, it seems strange not to do the same for clang.

ps I assume that Xcode 4 won't be held up until Lion is released so
these clang variants could be first done on Snow Leopard. It is unclear
from http://developer.apple.com/technologies/tools/whats-new.html
if the clang c++ support in Xcode 4.0 will use the existing libstdc++
or the new libc++ instead. It would be nice if it were the latter.
