When was the last ports tree that worked with RELENG_6?

I have a jail without sources under 6.3-STABLE. I copied all the content
of the /usr/src/usr.src/make/ directory from another machine with 8.3-RELEASE,
in that directory gave `make` command, then copied the "make" executable to
/usr/bin/ . I use current port tree and succesfully update
openssl, stunnel, pcre, exim.
