devel/gtexinfo/Makefile:
		   .if exists(/usr/bin/install-info)
		   IGNORE=                 "is included with your NetBSD distribution"
		   .endif

	   devel/rcs/Makefile:
		   ONLY_FOR_PLATFORM=      SunOS-*-*       # in NetBSD base system

   A simple solution for RCS would be something like

	   .if exists(/usr/bin/rcs)
	   IGNORE=  "is included with your NetBSD distribution"
	   .endif

Given that we want to maintain some consistency in these messages and
report already installed software, would it be useful to define
something in bsd.pkg.mk like (choose a better variable name):

	  INSTALLED_WITH_NETBSD="is included with your NetBSD distribution"

Then all the package-specific makefiles could use

	   .if exists(/usr/bin/XXX)
	   IGNORE=  ${INSTALLED_WITH_NETBSD}
	   .endif

and be consistent.
