app-text/texlive-2016 depends on dev-texlive/texlive-mathscience-2016, which conflicts with dev-texlive/texlive-science. app-office/lyx-2.2.2 depends on the later, making an update to app-text/texlive-2016 impossible.

(In reply to pavel sanda from comment #1) > Alexis, > could you have look, it seems to be realted to your recent commit > + || ( dev-texlive/texlive-mathscience dev-texlive/texlive-science ) yeah, this commit should have fixed it cc'ing portage team just in case it's due to portage not seeing the difference, but i think that's just due to an outdated portage tree
If you happen to have dev-texlive/texlive-science installed, the you'll have unmerge it: emerge --unmerge dev-texlive/texlive-science Otherwise, portage will prefer that package because it's installed.
Just to add some info that could be uselful, I had to "emerge -C dev-texlive/texlive-latex dev-texlive/texlive-basic dev-texlive/texlive-langenglish dev-texlive/texlive-langfrench" too.
