I have a gnome free setup. Now I need to install teams for some reason. Unfortunately that depends on gnome-base/gnome-keyring which depends to app-crypt/pinentry be installed with gnome-keyring support.
I do no accept such a basic security application than pinentry to be build with gnome-keyring support. That would blow the application and I risk to leak high confidential stuff to gnome accidentally.
So please make that dependency configurable via use flag as I see no reason why that should be a hard dependency at all.
