Just finished installing this. Upgrade took about 35 minutes total on my macbook air (2011). Was able to run a local Rails 4 app connecting to MySQL with no problems after the upgrade. Trying to install ruby 2.0-p247 now and all the gems and see what happens.

Isn't 2.0.0-p247 the system ruby? My rvm install was p195; after running "rvm use system" it's now p247 (ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13])

Is there nothing equivalent to virtualenv for Ruby? It'd be nice to be able to use the system Ruby and just get gem to install into an isolated project specific location.

Check out rbenv https://github.com/sstephenson/rbenv

I've been using rbenv. I didn't realize it could install gems without using sudo when the system Ruby is activated. Thanks!

rvm and its gemsets.

pythonbrew is actually the python equivalent of rvm - https://github.com/utahta/pythonbrew

Looks like you are right! Didn't expect it to have an up to date version of Ruby.

All worked fine. ruby 2.0-p247 compiled and install fine using rvm. Postgres backed Rails app worked too (using homebrew installed versions of postgres/mysql).
