Add the following lines to your /etc/make.conf
{{{
.if ${.CURDIR:M/usr/ports/www/firefox-nightly}
CC=clang
CXX=clang++
CPP=clang-cpp
.endif
}}}

Adjust the path to the port to your taste, but keep in mind that
this should be the realpath(1) of your port location.

For multiple ports you can use
{{{
.if ${.CURDIR:M<path1>}
I_WANT_CLANG=desperately
.endif

.if ${.CURDIR:M<path2>}
I_WANT_CLANG=desperately
.endif

.ifdef I_WANT_CLANG
CC=clang
CXX=clang++
CPP=clang-cpp
.endif
}}}
to avoid useless repetition.
