I did not trace down other dependencies but now looking a little (leaving options at defaults): devel/cmake needs devel/py-sphinx by default and devel/llvm80 needs both devel/cmake and devel/py-pshinx18 by default. (xorg need not bein involved: just building devel/llvm[16789]0 has the issue.) Thus the sequence for default options may need to be something like: *) Starting without textproc/py-sphinx18 installed A) build textproc/py-sphinx and devel/cmake and install devel/cmake ( py-sphinx can be via indirection through devel/cmake ) (cmake does not have a run-time dependency on textproc/py-sphinx as far as I can tell.) B) uninstall textproc/py-sphinx so that textproc/py-sphinx18 can be built and installed C) build textproc/py-shpyinx18 and devel/llvm80 and install devel/llvm80 ( py-sphinx18 can be via indirection through devel/llvm80 ) D) uninstall textproc/py-sphinx18 so that either textproc/py-sphinx* can be installed if needed E) build xorg. (Since I use devel/poudriere-develto build packages and then install just packages for things that I run, I do not have to do such explicit conflict management for build-time conflicts.) Of course, figuring out options to change the status of also may avoid having some of the dependencies and so avoid some conflicts. >> This is probably a dumb question, but is there some way >> to learn at the outset what conflicts need to be worked >> around?
