To any who may have had a problem building on OS X Lion. As has been noted elsewhere, the latest Apple compiler that is installed with xcode 4.4.1, llvm-gcc-4.2.1 is no longer able to build NetBSD toolchain.
Solution: install MacPorts gcc43 (gcc version 4.3.6 -/ MacPorts 4.3.6_3). Set in /etc/mk.conf file HOST_CC?= gcc-mp-4.3 HOST_CPP?= gcc-mp-4.3 No need to set HOST_CXX as the llvm-g++-4.2.1 works fine. You should now be good to go. -- Frank Zerangue frank.zeran...@gmail.com
