Are you trying to add NSS_ENABLE_ECC to the MAKE_ENV?

Normally you would put it in ports.conf as:

security/nss:   MAKE_ENV+= NSS_ENABLE_ECC=1

But this doesn't work. I tried setting CFLAGS+= NSS_ENABLE_ECC=1, and
that removed the default CFLAGS.  Instead you need to use:

cd /usr/ports
echo "security/nss: CFLAGS= "`make -V CFLAGS`" -DNSS_ENABLE_ECC" >>
