It's pretty easy to use current ports system with RELENG_4,
I do this sometimes. Just have following lines in /etc/make.conf:
# 4.x stuff
PTHREAD_CFLAGS= -D_THREAD_SAFE
PTHREAD_LIBS= -pthread
# may be, "ln -s /usr/local/etc/rc.d/rc.subr /etc/rc.subr" too
RC_SUBR= ${LOCALBASE}/etc/rc.subr
# only if we force port to use base system's port 5.005
PERL_VERSION= 5.00503
PERL_VER= 5.005
PERL_ARCH= ${ARCH}-freebsd
PERL5= ${DESTDIR}/usr/bin/perl${PERL_VERSION}
PERL= ${DESTDIR}/usr/bin/perl
Then, for perl, one needs small patch to bsd.ports.mk:
--- bsd.port.mk.orig Wed Oct 17 18:12:24 2007
+++ bsd.port.mk Sun Feb 24 00:33:48 2008
@@ -1420,8 +1420,8 @@

+PERL5?= ${LOCALBASE}/bin/perl${PERL_VERSION}
+PERL?= ${LOCALBASE}/bin/perl
.endif # !defined(_PERL_REFACTORING_COMPLETE)
This way, I continue to update small standalone mail servers
with new versions of security/clamav (those consoleless 4.11 boxes
have no hope to be upgraded to something newer).
Sometimes there is a need to patch port's Makefile a little,
f.e. when if redefines PTHREAD_LIBS unconditionally (bad, bad habit).
