Right. I think we knew that, and I recall Doug even mentioned it here a while back when it first came up. The Eigen folks (not entirely incorrectly) point to a broken toolchain, rather than forcing themselves to accomodate the busted old g++ 4.2.1. But it is somewhat orthogonal to the CRAN / R world where another set of people decides which compiler is deemed official. At the end of day, and to me as a non-user of OS X, this just seems to make working on OS X as tedious as working on Windows where you have to patch your system together in bits and bobs. I guess I am spoiled rotten by 15+ years of dpkg and apt-get and "things just working".
