I use a simple script to set and export the PKG_PATH variable.

# Set PKG_PATH and PKG_CACHE
# $Id: PKGenv,v 1.2 2009/01/11 12:29:54 j65nko Exp $ 

# ------------------------------
# IMPORTANT use "." to source this script!!!
#
#    . ./PKGenv
# ------------------------------
# The PKG_PATH variable needs to be set
# and exported in the current shell/xterm !

# 'sh ./PKGenv' will not work! 

if [ "$(id -u)" -ne  0 ]; then 
    echo PKGenv : Remember you are not ROOT !! 
fi

export PKG_CACHE

You source it like this

$ . ./PKGenv
j65nko@hercules[~]. ./PKGenv 

PKGenv : Remember you are not ROOT !!

OpenBSD 4.2 (GENERIC) #1179: Tue Aug 28 10:37:50 MDT 2007

Current settings
------------------------------------
PKG_CACHE=/home/packages/
PKG_PATH=ftp://ftp.plig.org/pub/OpenBSD/4.4/packages/i386/
------------------------------------

The script is attached for download. Just do a "mv PKGenv.txt PKGenv" to get rid of the ".txt" extension.
