The nice thing about having a real OS X installation is that I can run the test suite against that too and be ensured that I did not break anything for others while developing on a faster newer Ruby myself. Therefore, it would be great if the system Ruby gets some love in the form of:

• Pre-installed Bundler. Even though it’s not part of a normal system installation, a lot of projects will need it to run their test suites, even Objective-C projects. E.g. libPusher.
• Updated RubyGems, which is needed to install the latest Bundler.

The pre-installed (with RVM) Ruby 1.9.3 version has a couple of issues:

• The RVM version installed is outdated (I think) and does not support the --fuzzy flag etc.
• I need to source ~/.rvm/scripts/rvm myself, otherwise I get: RVM is not a function, selecting rubies with 'rvm use ...' will not work.. This probably means the profile of the user running the build is missing the required RVM setup.
• I need to configure OpenSSL to use a valid root CA file, as described in this comment, otherwise it won’t be able to verify connections.
• I need to symlink /usr/bin/gcc-4.2 to /usr/bin/llvm-gcc-4.2, otherwise this happens. Note that this not a RVM issue perse, it will probably occur while installing other tools as well.

The build script sources .profile, so it is a good place to put symlinks and stuff

Good point about RVM

I have not changed anything on the VMs, this is how they were when I first started working on them. I did notice the MacPorts/Fink warning.

So, when I figure out how to update the VMs, here's what I think I'll do:

• Update RVM and add it to .profile
• Update system RubyGems and install bundler
• Uninstall MacPorts and/or Fink
• Set RVMs default ruby to be the system ruby
• Preinstall Ruby 1.8.7 and 1.9.3
• Update Xcode

Eventually, I'll also look into preinstalling CocoaPods and run pod setup so we have the spec repo cloned and all.

Anything you think I should add/remove?

Michal Papis just told me that llvm really shouldn't be used to compile rubies or gems. See this ruby bug.

@joshk - rvm by default installs latest rubygems/bundler, as for homebrew you can run: rvm requirements run force ruby - it wll detect hombrew and install what is required for ruby - replace the last argument with what you need

Oops, didn’t see the newer messages.

@henrikhodne That list sounds excellent.

Regarding the LLVM issue, it’s true that older Rubies will have problems, but since 1.9.3-p125 it should work (see the release notes: http://www.ruby-lang.org/en/news/2012/02/16/ruby-1-9-3-p125-is-released/).
