I've only used socks4, but I imagine that socks5 is similar.  Reading the
"How_to_SOCKSify" document in the source distribution, I added :

  CPPFLAGS+= -Dconnect=Rconnect -Dgetsockname=Rgetsockname -Dbind=Rbind -Daccept=Raccept -Dlisten=Rlisten -Dselect=Rselect
  LDADD+= -L/usr/pkg/lib -Wl,-R/usr/pkg/lib -lsocks4

to the Makefile for sup/sup and compiled it.  I installed it as rsup and it
works perfectly.  I've also done the same for ssh and scp (installed as
rssh and rscp).  For pkgsrc programs that use configure (e.g. ircII), I
added :

  CONFIGURE_ARGS=--with-socks4=/usr/pkg/lib

to /etc/mk.conf.  I had to `cd /usr/pkg/lib; ln -s libsocks4.a libsocks.a`
because configure looks for -lsocks.

To check if things are working, you could run

	tcpdump host <socks-serer>

or

	tcpdump host <real-host>

to see which way packets are going.
