I strongly disagree. Clang works excellently. Here's my way to build NetBSD 
(does not need command line tools being installed, Xcode in /Applications is 
sufficient):

#!/bin/csh
set     MACHINE=amd64
set     DIST=${cwd}
set     SRCDIR=${cwd}/src
set     TOOLDIR=${cwd}/tools
set     X11SRCDIR=${cwd}/xsrc
set     OBJDIR=obj.${MACHINE}
set     JOBS=`sysctl -n hw.ncpu`
set     BUILD="./build.sh -j${JOBS} -U -N0 -u -x -X${X11SRCDIR} -m${MACHINE} 
-T${TOOLDIR} -O${OBJDIR}"
set     XCODE=/Applications/Xcode.app/Contents/Developer
set     HOST_CFLAGS=-O2\ -pipe\ -march=core2\ -fomit-frame-pointer\ 
-fno-stack-protector
set     HOST_CPPFLAGS=-isysroot\ 
${XCODE}/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk
set     
HOST_LDFLAGS=-Wl,-syslibroot,${XCODE}/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk
set     HOST_CC=${XCODE}/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
set     HOST_CXX=${XCODE}/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++
cd      ${SRCDIR}
${BUILD} -V HOST_CC="${HOST_CC} ${HOST_CPPFLAGS}" -V HOST_CXX="${HOST_CXX} 
${HOST_CPPFLAGS}" -V HOST_CPPFLAGS="${HOST_CPPFLAGS}" -V 
HOST_CFLAGS="${HOST_CFLAGS}" -V HOST_CXXFLAGS="${HOST_CFLAGS}" -V 
HOST_LDFLAGS="${HOST_LDFLAGS}" release

Kind regards,
Adam
