Comment(by ryandesign@…):

 We already know that cairo will not work correctly when compiled with
 clang or llvm-gcc-4.2, which is why the port forces the use of gcc-4.2.
 However, on Xcode 4.2, there isn't supposed to be a gcc-4.2, so the port
 is supposed to use the apple-gcc42 port in that case. But since you've
 somehow restored gcc-4.2 onto your system, the port is using it.

 Try installing the apple-gcc42 port and using it compile cairo:

 {{{
 sudo port install apple-gcc42
 sudo port clean cairo
 sudo port install cairo configure.compiler=apple-gcc-4.2
 configure.cxx=g++-apple-4.2
 }}}

 See ProblemHotlist#xcode42.

 Several other ports use the same programming to force the use of gcc-4.2;
 these might also fail because of your rogue gcc-4.2/gcc-4.0 compilers, so
 I recommend you remove them. If you need the Apple versions of gcc while
 using Xcode 4.2, consider using the compilers installed by the apple-gcc42
 /apple-gcc40 ports. These should be slightly newer versions that should
 work on Lion.
