emacs-app @23.3 fails compiling with "unexec: input file not in Mach-O format" error

[philippe.bernery@…]

I use MacPorts on Lion with Xcode 4.2.

I found a similar ticket about emacs @22 (​http://trac.macports.org/ticket/24913) and applied the given patch. The compilation went further but failed at some point. Here is an extract of the error:

I tried with both clang (the default) and llvm-gcc-4.2 compiler.
