System: NetBSD stats3..... 6.1_STABLE NetBSD 6.1_STABLE (SD_VMT_TWEAK) #0: Mon Aug 22 17:31:39 CEST 2016  root@stats......:/b/obj/sys/arch/i386/compile/SD_VMT_TWEAK i386

	I'm using "pkgin" and binary packages for upgrade.

	It appears that in certain situations when doing "pkgin
	full-upgrade", pkgin can end up emitting this error message:

	pkgin: empty non-autoremovable package list

	For a naive system administrator this message may appear quite
	meaningless, and it gives no hint as to what might be the
	actual root cause of this problem -- whether it's a particular
	package which is installed (which one?) which causes the
	problem or ...

	As it turns out, this problem appears to be fixable with
	either "pkg_admin rebuild" and/or "pkg_admin rebuild-tree",

	However, there is nothing in the error message which suggests
	this might be the problem.  The error message is therefore
	... unhelpful and should most probably be improved.

	See above.

	I'm not entirely certain what brought me into this situation;
	it's conceivable it's a consequence of an earlier "pkgin fug".

	Improve error message, hint at dependency database rebuild?
