+# defaults/truffleruby. However, TruffleRuby < 24 defines
+# REUSE_AS_BINARY_ON_TRUFFLERUBY directly in its copy of
+# lib/rubygems/platform.rb, so it is not defined if RubyGems is updated (gem
+# update --system). Instead, we define it here in that case, similar to
+# bundler/lib/bundler/rubygems_ext.rb. We must define it here and not in
+# platform.rb because platform.rb is loaded before defaults/truffleruby.
