I compile a 64bit CLI version of the current R-devel from svn, with about 1000 add-on packages, in Lion, using the clang and clang++ compilers
from the LLVM project (and gfortran 4.7). This generally works well, the compiles are really fast, but for RcppArmadillo I get
** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) :
