Sure, follow my src.conf:

.if !defined(CC) || ${CC} == "cc"
CC=clang
.endif
.if !defined(CXX) || ${CXX} == "c++"
CXX=clang++
.endif
.if !defined(CPP) || ${CPP} == "cpp"
CPP=clang-cpp
.endif
# Don't die on warnings
NO_WERROR=
WERROR=
# Don't forget this when using Jails!
NO_FSCHG=

and my make.conf

KERNCONF=MURPHYS

WITH_OPTIONS=yes
WITH_VIM_OPTIONS=yes
WITHOUT_X11=yes

# added by use.perl 2011-12-12 13:19:26
PERL_VERSION=5.12.4
