This is an interesting something.

Firstly, assuming you have XCode installed, you can install RcppEigen by:

R> install.packages("RcppEigen", type="source")

and it compiles fine.

It is interesting because there are other projects (outside of the R
universe) that use Eigen, but can't be compiled on OS X w/o using a
more modern version of gcc than OS X uses.

I probed the authors of that (other) library to see what gives, but
they essentially pointed out that even the Eigen devs suggest to use a
newer version of gcc, even though their main page only suggest gcc 4.2
or newer.
