 Replying to [comment:47 alex.hanselmann@…]:
 > I question the scope of the bug? I just updated to MacPorts 2.3.0 on a
 OSX 10.7.5 computer. The compiling of ld64(ld64-236.3) fails too. The
 using of Clang-3-4 as a solution fails too.

 This bug affects users of later OS X versions if their default C++
 compiler is not clang.  I think that includes Lion users using a version
 of XCode earlier than about 4.3 or 4.2.  If you don't want to update your
 XCode I would expect that compiling with macports-clang-3.4 would work.

 > make -j2 -w all CC="/usr/bin/llvm-gcc-4.2" CXX="/usr/bin/llvm-g++-4.2"
 OTHER_CPPFLAGS="-I/opt/local/include" OTHER_CFLAGS="-Os -arch x86_64"
 OTHER_CXXFLAGS="-Os -arch x86_64" OTHER_LDFLAGS="-L/opt/local/lib
 -Wl,-headerpad_max_install_names -arch x86_64" RC_SUPPORTED_ARCHS="armv6
 armv7 i386 x86_64" LLVM_CONFIG=/opt/local/bin/llvm-config-mp-3.3.

 That says that it is using `llvm-gcc-4.2` (the default compiler in XCode
 4.1).  Unfortunately ld64 @236.3_1 does not compile with that compiler.
 If you haven't done so already, you might try this:
 {{{
 sudo port clean ld64
 sudo port upgrade ld64 -llvm33 +llvm34 configure.compiler=macports-
 clang-3.4
 }}}

 I've also attached a simple patch for the conflicting blacklist in the
 Portfile, which should prevent it from trying that compiler by default.
