Hello,
in Fedora, there's a patch which is supposed to modify upstream behaviour
for paths which are using ruby_version config entry. Preferably replaced
by the `ruby_version_dir_name` config entry, if it's not empty. This
behaviour was broken (it was checking for `nil`), so I fixed the patch.
This leads to a versioned gem path in `~/.local`.
Please take a look here:
