USE="grammar jpeg ots pdf readline svg thesaurus" If dev-libs/libxslt is installed, /usr/lib/abiword-2.6/plugins/libAbiLaTeX.so depends on libxslt.so.1 after emerging abiword-plugins. If libxslt is not installed - no dependency. I am not sure whether this dependency is necessary, but the ebuild should probably either take some measure for removing this dependency, or add dev-libs/libxslt to RDEPEND. It's a problem if running emerge --depclean --with-bdeps n. Reproducible: Always
This should be solved now with abiword-2.8.6 (depending on "latex" USE flag)
