Comment (by ryandesign@…):

 I originally thought the problem must be that with Xcode 4 you would be
 using llvm-gcc-4.2. But that's not the case because the boost port already
 blacklists llvm-gcc-4.2. So with Xcode 4 boost is using gcc-4.2, same as
 on Xcode 3. And according to XcodeVersionInfo#MacOSX10.6, Xcode 3.2.6,
 4.0, and 4.1 use the same version of gcc-4.2: 5666 dot 3. So I'm at a loss
 to explain why it would fail with Xcode 4, and also our usual compiler
 blacklisting methods could not be used to work around this, since they
 work by looking at the compiler version number.
