A lot of ports can't be build with clang. You can add something like
this to your /etc/make.conf (modifying paths accordingly) :
.if ${.CURDIR:M/usr/src*} ||
${.CURDIR:M*/usr/ports/emulators/virtualbox-ose-kmod*}
.if !defined(CC) || ${CC} == "cc"
CC=clang
.endif
.if !defined(CXX) || ${CXX} == "c++"
CXX=clang++
.endif
NO_WERROR=
WERROR=
.endif

That's what I use. Note the first if statement.

Cheers
