That has been explained a number of times, eg in the different SO question
(eg even the one ref'ed by JJ is a duplicate). An earlier one is
In short, R "writes down" the values of CC, CXX, CFLAGS, .. seen at _its_
compile time and uses it each time R CMD ... is invoked.
That works, as on most sane operating systems you assume that 'cc' or 'gcc'
will always point to a working compiler. OS X is, ahem, different. And so
it breaks, at least until the default R build catches up with the tool chain.
Really a question for r-sig-mac and the OS X users here to sort out.
