IMHO there should be exactly one instance for describing a package.
And this instance is PKGBASE, of course. PKGPATH is just a way to
minimally _categorize_ them and organize sources in CVS, no more.
Example with graphics/gqview-devel doesn't show anything IMHO because
its PKGNAME can easily be renamed to, say, gqview-devel (from gqview).
In this case binary upgrade will be possible without preserving
information from where this package was built (PKGPATH) and without
additional analisis. PKGBASE should be enough for upgrade.
I don't see any problem in keeping PKGBASE uniq in entire pkgsrc
tree. While not doing this is a bit painful and makes some
restrictions on how upgrades can be done. It also limits me/user to
the current pkgsrc/ structure. It is not good, but...sometimes it
changes in any case.

Ok. I see. You use PKGBASE+PKGPATH as a package "identifier".
I propose to use only PKGBASE. Because
1) PKGPATH is necessary only for source-based upgrades.
For binary upgrades it is easier to not check PKGPATH at all.
It is possible to check PKGPATH too, I don't see any reason for
Renaming packages (glib -> glib1, python -> pythonXX etc.)
is a very different story and also has EASY solution.
2) It makes easier package manipulation for the third party software.
One simple example. I recently wrote wip/pkg_online - client/server
tool that provides
search capabilities in pkgsrc packages. Central part of it
is PKGNAME (actually PKGBASE) through which everything is done.
Suppose I want to see full information about package gqview.
I do this like the following
pkg_online_client -i gqview
Instead of showing me information about ONLY ONE package I query,
it shows me information about three packages: graphics/gqview-gtk1,

This algorithm is trivial only for those people who name package using
two instances ;) It think single PKGBASE is enough for most cases. The
only reason to use additional PKGPATH is a source-based upgrades.
