Xcode 4.2, like Xcode versions before it, comes with more than one compiler. llvm-gcc-4.2 is one of them, but it also includes clang; clang is the default even. So if the problem is, as the comment states, that Xcode 4.2's clang miscompiles mpfr, then you need to use the compiler_blacklist_versions portgroup to blacklist Xcode 4.2's version of clang. _______________________________________________ macports-dev mailing list macports-dev@lists.macosforge.org https://lists.macosforge.org/mailman/listinfo/macports-dev
