This package has the following RDEP specified: sys-devel/llvm However, given the slotted nature of LLVM in Gentoo and the fact that it is a prebuilt binary package, I seriously doubt it actually requires files installed by our LLVM package. Please check if the dep is really meaningful.
I checked and now it is not depending on anything from llvm. The only dependency I have found is on libclang.so I will omit llvm from the dependency and only leave clang
I think it uses the one it bundles anyway: gnat-gpl-2016-x86_64-linux-bin/lib/gps/libclang.so
I removed the bundled libclang.so and used the one in the system. The bundled one is supposed to be built with the llvm 3.5.2 source tree, so I guess I should depend on the slot 0 of sys-devel/clang. But actually gps-bin run here even with slot 4 of clang, even if I am not sure it exercise the functionality that are on that library. And more over, I have added dev-ada/gps-2017 on the tree, that build fine. So gps-bin is going to die; I would like to leave dev-ada/gps-bin-2016 on the tree for some more time, without stabilizing, and then drop
