In the past, Bundler used to respect the way Gentoo Linux sets up Ruby (abridged output):
$ gem env
RubyGems Environment:
- RUBYGEMS VERSION: 3.1.6
- RUBY VERSION: 2.7.5 (2021-11-24 patchlevel 203) [x86_64-linux]
- INSTALLATION DIRECTORY: /usr/lib64/ruby/gems/2.7.0
- USER INSTALLATION DIRECTORY: /home/xhire/.gem/ruby/2.7.0
- GEM CONFIGURATION:
- "install" => "--install-dir /home/xhire/.gem/ruby/2.7.0"
- "uninstall" => "--install-dir /home/xhire/.gem/ruby/2.7.0"
- "update" => "--install-dir /home/xhire/.gem/ruby/2.7.0"
As you can see, it makes gems installed to a user’s directory, not system-wide. However, bundler doesn’t respect that:

Your user account isn't allowed to install to the system RubyGems.
You can cancel this installation and run:
bundle install --path vendor/bundle
to install the gems into ./vendor/bundle/, or you can enter your password
and install the bundled gems to RubyGems using sudo.

Man page bundle-install(1) says:
By default, Bundler installs gems to the same location as gem install.
This is not true.
To fix this misbehaviour, add a line similar to the following one (change your username and the version) to a shell startup script like ~/.bash_profile or similar (depending on the shell you use):
export GEM_HOME=/home/xhire/.gem/ruby/2.7.0
