^^ the actual error is here - it cannot find libR

This is just a consequence of the above, _xerbla_ is not found as it  
is defined libR which couldn't be loaded. The reason is that the  
framework install didn't set the correct path in libRlapack. It is  
now fixed in the current R-devel.

The current R-devel now also checks the Xcode capabilities and will  
fall-back to flat namespaces if the linker is too old (the other  
error reported here). I tested some combinations of BLAS and tools,  
but not all of them, so please drop me a line if you find a setup  
that doesn't work.

Thanks,
Simon
