Your system header files appear to assume that the compiler defines ___builtin___stpncpy_chk. Your compiler appears to not define that function. gcc as normally distributed does not define any sort of ___builtin___stpncpy_chk function. However, evidently the OS X 10.7 header files expect it to. What program are you running as "gcc"? Is it possible that it is out of date with respect to the header files? For any other ideas, you are going to have to ask somebody familiar with Darwin. Ian
