enblend @4.0.3 compilation error with llvm/Xcode 4.2

[philippe.bernery@…]

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:
