The difference above is that the latter student has probably an ancient Xcode installed (2.x) whereas we recommend Xcode 3.x (and require it for compatibility with CRAN binaries).

Very, very good -- thank you! 

I took this opportunity to add this to the Rcpp-FAQ as the following.
Corrections or suggestions welcome.  We did just wrap up 0.9.3 which should
hit CRAN either today or tomorrow so this won't be in it yet.


\subsection{I am having problems building Rcpp on OS X, any help ?}

OS X is a little more conservative with compiler versions, so it pays to get
the latest of whatever Apple releases which may already be a little behind
what is used on Linux or Windows.

At the time of writing this paragraph (in the spring of 2011), \pkg{Rcpp}
(just like CRAN) supports all OS X releases greater or equal to 10.5.
However, building \pkg{Rcpp} from source (or building packages using
\pkg{Rcpp}) also requires a recent-enough version of Xcode; the current
version is 3.1.4 which can be downloaded free of charge from the Apple
Developer site.
