There is already a ticket open.
    http://trac.macports.org/ticket/29840

But I don't know why the compiler is broken.

Thank you. After adding the same patch as in wine:

if {${configure.compiler} == "llvm-gcc-4.2" ||
    ${configure.compiler} == "clang"} {
    configure.compiler gcc-4.2
}

(except that I only wrote "configure.compiler clang") fontforge
compiles just fine now.

I tried that, but I was unsuccessful. What exactly do I need to change?

Thank you, I'm looking forward for that.
