Interesting, I don't actually see the error message in the log.

Things to try:

• updating the port to 0.5.7
• building with clang or gcc-4.2 instead of llvm-gcc-4.2
• not building universal
• not building parallel

I verified that msgpack 0.5.4 builds with gcc-4.2 and clang on Snow Leopard with Xcode 3.2.6, but not with llvm-gcc-4.2; the error looks like yours.

I tried updating the port to 0.5.7 and now trying to build with llvm-gcc-4.2 hangs with 100% CPU use compiling object.o.

So I suggest we modify the port to use clang instead of llvm-gcc-4.2. I'll attach a patch.

proposed patch

Confirmed that clang works on my system as well.

I was able to build msgpack 0.5.7 for i386 using:

./configure CC="clang" CXX="clang" CFLAGS="-arch i386" CXXFLAGS="-arch i386"
make
make install
