Conan Ruby 3.2.2 darwin tarballs: rubygems.rb eager spec_fetcher require breaks Bundler default gem activation & strip AppleDouble files #5666

Context

While verifying the macOS ARM64 (ruby-3.2.2-darwin-arm64.tar.gz) and Intel (ruby-3.2.2-darwin.tar.gz) portable Conan Ruby packages in s3://openstudio-resources/pat-dependencies3/ for NatLabRockies/OpenStudio-PAT#311, we identified two upstream packaging issues in the Conan Ruby 3.2.2 build/archive:

1. Custom lib/ruby/3.2.0/rubygems.rb modification pre-activates securerandom 0.2.2 before Bundler runs

In the Conan Ruby 3.2.2 build (ruby/3.2.2#e349279c358fd8f54d83446a3af8ecfe), lib/ruby/3.2.0/rubygems.rb replaces upstream Ruby's autoload declarations with eager require calls at the bottom of rubygems.rb (lines 1397–1406) before Gem::Specification.load_defaults runs:

require 'rubygems/config_file'
require 'rubygems/BundlerVersionFinder' # ...
require 'rubygems/spec_fetcher'

Because rubygems/spec_fetcher requires rubygems/remote_fetcher -> resolv -> securerandom, and Gem::Specification.load_defaults has not yet registered the default gems, Ruby loads securerandom from stdlib and then registers securerandom-0.2.2 as an already-activated default gem specification once load_defaults executes.

When OpenStudio-server subsequently runs Bundler.setup with a Gemfile.lock that locks securerandom (0.4.1), Bundler raises:

Gem::LoadError: You have already activated securerandom 0.2.2, but your Gemfile requires securerandom 0.4.1. Prepending `bundle exec` to your command may solve this.

Fix: Either restore upstream Ruby 3.2.2's autoload :SpecFetcher, "rubygems/spec_fetcher" in lib/ruby/3.2.0/rubygems.rb, or ensure Gem::Specification.load_defaults runs before any eager require of rubygems/spec_fetcher.

2. macOS ._* AppleDouble resource fork files in ruby-3.2.2-darwin-arm64.tar.gz

ruby-3.2.2-darwin-arm64.tar.gz in s3://openstudio-resources/pat-dependencies3/ was archived on macOS without COPYFILE_DISABLE=1, leaving ._* AppleDouble files throughout ruby/.
Fix: Repackage ruby-3.2.2-darwin-arm64.tar.gz (and any macOS dependency tarballs) with COPYFILE_DISABLE=1 tar -czf ....
