Using compilers from MacPorts and similar suites (Darwin ports, Fink  
etc.) is strongly discouraged (and outright not supported by the CRAN  
binary) since they have been known to be badly broken in the past and  
when whenever tested so far they were incomplete and incompatible. You  
have to re-compile R yourself with those tools (and you're entirely on  
your own) if you really want to use them. CRAN binaries work only with  
Apple's gcc branches, if you want to use anything else, you have to  
follow the unix R instructions and compile everything from sources.
