sounds like a portage "bug": it should prefer dev-ml/camlp4 (leftmost part of the || ) for lablgl when ocaml-4.02 is pulled in for other reasons BTW., already 'emerge -v1 findlib' fails with:
root@caiman:/root(35)# emerge -v1 findlib
These are the packages that would be merged, in order:

The dep_zapdeps function needs some new heuristics to handle || ( dev-ml/labltk:= <dev-lang/ocaml-4.02[tk] ) deps from dev-ml/lablgl-1.05. The new heuristics can make use of the _want_update_pkg method to detect whether a dev-lang/ocaml upgrade is desired, and avoid the <dev-lang/ocaml-4.02[tk] choice in that case. Now I have this slot conflict only on systems with app-text/kbibtex-0.5.1 (depending on dev-tex/bibtex2html-1.98).

(In reply to Juergen Rose from comment #4) > Now I have this slot conflict only on systems with app-text/kbibtex-0.5.1 This appears to be a separate issue, because it does not involve the || ( dev-ml/labltk:= <dev-lang/ocaml-4.02[tk] ) deps from dev-ml/lablgl-1.05. Please file a new bug. (In reply to Zac Medico from comment #3) > The dep_zapdeps function needs some new heuristics to handle || ( > dev-ml/labltk:= <dev-lang/ocaml-4.02[tk] ) deps from dev-ml/lablgl-1.05. The > new heuristics can make use of the _want_update_pkg method to detect whether > a dev-lang/ocaml upgrade is desired, and avoid the <dev-lang/ocaml-4.02[tk] > choice in that case. In the following branch I have a test case to reproduce the problem: https://github.com/zmedico/portage/commits/bug_531656 I also started working on some heuristics to help it converge on the desired solution, but the changes currently break SlotConflictUpdateTestCase. In my bug_531656 branch on github I have a patch which I've posted for review here: http://thread.gmane.org/gmane.linux.gentoo.portage.devel/5040 This is in the master branch now: https://github.com/gentoo/portage/commit/a9064d08ef4c92a5d0d1bfb3dc8a01b7850812b0 There MIGHT still be an issue here in portage-2.2.16. I still had blockers from dev-ml/lablgl and dev-ml/lablgtk for various emerge commands I tried to get these upgrades through. It got resolved for me only after explicitly running emerge -1va camlp4 ocaml findlib lablgl lablgtk BUT! I didn't run emerge --update --newuse --deep --with-bdeps=y @world again until later, and this command might have figured out how to proceed, too late to find out for me now. I'm not 100% clear on what the patch would do, if anything, for my regular emerge commands.
