We have just managed to change the license under which llvm/libc++ is released. It is now dual licensed under *both* the UIUC and MIT license.  The code can be used under either license (see the top of the file), LICENSE.txt contains the full wording of both licenses.  The MIT license does not contain the binary redistribution clause.

More details here:

http://llvm.org/docs/DeveloperPolicy.html#license

It is our hope that this will ease the concerns expressed here regarding compatibility with the boost license.
