# Typically, GEM_HOME points to $HOME/.gem/ruby/version_without_patch. For example, for Ruby 3.2.2, it would be
# $HOME/.gem/ruby/3.2.0. However, chruby overrides GEM_HOME to use the patch part of the version, resulting in
# $HOME/.gem/ruby/3.2.2. In our activation script, we check if a directory using the patch exists and then prefer
# that over the default one.
