Thus -flto and -O4 do not work in llvm-gcc42. Either provide a custom linker for use with llvm in macports or simply make libLTO.dylib available to the system linker by placing a symlink to /opt/local/lib/libLTO.dylib in /usr/lib/. The second option would make LTO/bitcode linking available globally but would leave the existing XCode llvm installation in /Developer/usr/ unaffected.
