As a result

Code: Select all

cat /etc/portage/profile/package.provided/app-emacs\:\:project.conf 
app-emacs/project-0.11.1

lets app-emacs/rustic work flawlessly without external package app-emacs/project-0.11.1 to be installed.

Any idea how to detect which app-emacs/* packages can be uninstalled but declared as installed instead?

I'm not sure I understand the question. app-emacs/rustic isn't in ::gentoo, but it sounds like you believe it has incorrect dependencies.

Looking at its Cask file, it really does depend on project, but project is also bundled in Emacs. Your app-emacs/project (which is also not in ::gentoo) may be newer than the version bundled in Emacs though, as the versions included in Emacs only get updated every so often (I think the frequency depends on the package). So, it's not strictly unnecessary, just means you're not necessarily getting newer features.

I'm not aware of a list of packages that are "dual life" (like in Perl where you also have modules in Perl itself but on CPAN too) in Emacs.
