Sorry for the noise.
But when I tried to compile essential ports (essential to me), like=20
x11-wm/windowmaker, mulitmedia/ffmpeg, for instance, I run into serious=20
compiler/assembler error with LLVM/CLANG. I guess the ports- tree isn't=20
mature for clang. So am I right in this thinking: leaving /etc/make.conf =
untouched in terms of not putting there the CLANG build construct and=20
putting this instead into /etc/src.conf will only affect the OS' source=20
tree to be build by clang and all ports are build by the antique=20
system's gcc 4.2.1?
