[gentoo-user] please explain this contradictory(?) emerge dependency

[Allan Gottlieb]

I get dependency problems in my normal update world that I can't
understand.  The entire output is below.

As far as I can tell gnome-2.32.1-r1 (which is installed) is requiring
packages from gnome-3, which must be wrong.  I don't see any such
dependencies in the ebuild for gnome-2.32.1-r1 and there is an "official
mask list" (which I am using) for those of us who want to
delay installing gnome-3 for a while.

My conclusion that gnome-2... is requiring gnome-3 packages (which I
know is wrong) comes from two points in the output below.

1.  The indenting of the --tree --verbose output seems to say this
    (e.g., the first two lines say gnome-2... depends on nautilus-3)

2.  The comments related to mask changes at the bottom say
    evince-3... is required by gnome-2...

Please help.
thanks,
allan

Without doing any digging (I'm 100mi away from my Gentoo boxes and
sitting on satellite internet, so SSH is painful), I would presume the
packages pulling in those dependencies aren't specifying a maximum
version, so it's not that they're "requiring" gnome 3 packages,
they're requiring gnome packages and are choosing to use the newest,
which happens to be part of 3, meaning the gnome 2 ebuilds would need
updated to require version < 3.0 to avoid it automatically, and
possibly block on mixing 2 and 3 if the mixing really does give
issues.

In /etc/portage/package.mask (untested, for the aforementioned reasons), add:
>=gnome-base/nautilus-3
>=app-text/evince-3

All the gnome-3 packages are masked (package.mask).

Indeed, at the end of my output (see prev msg) you see recommendations
from emerge for me to remove some masks.

It was more subtle than I thought.  A big tip from Alexandre Rostovtsev
suggested that the problem might be that some package other than
gnome-base/gnome might be requiring nautilus-3 *OR introspection*.

Sure enough the new evince was the culprit.  I put in a workaround for
today but everything should be fine tomorrow due to ...

    Great.  So tomorrow, my resync will find nautilus...-r2 and I will be
    able to remove
        app-text/evince -introspection
    from package.use.
    (That is the workaround I put in today to permit an update world to
    proceed without gnome-3).

Case closed!

Cool!

A perfect example why we ought to report on bugs. It might save someone
else from a teeth-gritting hardship, even when handling a totally unrelated
package.

Well done, Gentoo-ers :-)
