cd /usr/ports as normal
have a look at man mount_unionfs
your basically stacking fs on top of each other
writes goto the tmpfs as its at the top of the stack
its not persistent over boots mind

quicker to do
mv /usr/ports /usr/ports.real
mkdir /usr/ports
mount -t tmpfs tmpfs /usr/ports
mount -t unionfs -o noatime /usr/ports /usr/ports.real
of cause tmpfs can actually start using disk space unlike a md
device so if you eat up to much ram with the compiles it will slow
down
