"pkg_info -I" checks against both the installed packages *and*
	the packages in PKG_PATH.   This cause the check-conflicts target
	of Mk/bsd.port.mk to generate false positives.

Fix: Use "pkg_info -e" to eliminate the false positives.
How-To-Repeat: 
	Attempt to install / reinstall xterm-206_1.  This conflicts
	with xorg-clients-6.8.2 (not xorg-clients-6.8.2_1 which is
	installed).  Note xorg-clients-6.8.2.tgz is available as a
	package but is not installed.
