 Enblend is not compiling with llvm (comes with Xcode 4.2).

 As suggested in the mailing list, I changed the compiler to llvm-gcc and
 it works. I use this command line to compile enblend:

 sudo port install enblend configure.compiler=llvm-gcc-4.2


 Here is an extract of the error that happened before the compiler change:
