Most likely you will need to upgrade your Xcode.  Do you have gcc-4.2
which is the default on newer systems?  Older versions of Xcode had
gcc 3.something as well as 4.0, whereas newer versions have gcc 4.0 as
well as gcc 4.2.

If I was better at remembering the Apple build numbers for the
compiler, I could tell you for sure.
