on ftp://ftp.netbsd.org/pub/NetBSD/packages/1.5/i386/All, we have the
	wollowing files:

-rw-rw-r--  1 1127  netbsd   99544 May  7  2001 gd-1.8.3.tgz

-rw-rw-r--  1 1127  netbsd  208935 May  7  2001 png-1.0.10.tgz
-rw-rw-r--  1 1179  netbsd  210187 Aug  1 13:01 png-1.0.11.tgz

	gd depends on png>1.0.9, however, it does not work with png-1.0.11
	(only works with png-1.0.10) due to shared library version number
	change.  therefore, if we use command lines like
	% pkg_add ftp://ftp.netbsd.org/pub/NetBSD/packages/1.5/i386/All/gd
	pkg_add end up installing png-1.0.11 and gd-1.8.3, which makes gd
	non-working.  i'm not sure what should be done about this.
