I'm trying to understand the explanation of this but I don't quite see it. It

Multiple package instances within a single package slot have been pulled!!! Into the dependency graph, resulting in a slot conflict: dev-libs/openssl:0 (dev-libs/openssl-1.0.1g::gentoo, ebuild scheduled for merge) pulled in by =dev-libs/openssl-1.0.0:0-bindist required by (net-dns/bind-9.9.4p2::gentoo, ebuild scheduled for merge) dev-libs.


looks like conflicting libraries used by gimp, inkscape and openoffice.

  2. Slot conflicts can be annoying. It's worse when an attempt to fix them leads to an even bigger mess. I hope this post helps you with some cases - and that portage will keep getting smarter about resolving them automatically.

I don't quite understand the explanation, and what my options are.

Conflict

Explanation:

New USE for 'app-text/poppler-bindings:0' are incorrectly set. In
order to solve this, adjust USE to satisfy '~app-text/poppler-
bindings-0.10.4[gtk,cairo]'.

app-text/poppler:0

('ebuild', '/', 'app-text/poppler-0.10.5-r1', 'merge') pulled in by
~app-text/poppler-0.10.5 required by ('ebuild', '/',
'app-text/poppler-bindings-0.10.5-r1', 'merge')
(and 1 more)

('installed', '/', 'app-text/poppler-0.10.4', 'nomerge') pulled in by
~app-text/poppler-0.10.4 required by ('installed', '/',
'dev-tex/luatex-0.30.3', 'nomerge')
~app-text/poppler-0.10.4 required by ('installed', '/',
'app-text/poppler-bindings-0.10.4', 'nomerge')
~app-text/poppler-0.10.4 required by ('installed', '/',
'app-office/openoffice-3.0.0', 'nomerge')
(and 3 more)


It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in the
dependencies of two different packages, then those packages can not be
installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man page
or refer to the Gentoo Handbook.
