Question: I just installed using:

rvm install 1.9.2-head

and it used: http://svn.ruby-lang.org/repos/ruby/branches/ruby_1_9_2

And:

$ ruby -v ruby 1.9.2p0 (2010-08-18 revision 29034) [x86_64-darwin10.4.0]

So I am good to go, right?

I get this from `ruby -v` (having installed 1.9.2):

    ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]

So, the revision number is very slightly different. Hard to say in this case whether that is worth uninstalling the one and installing the other. Probably not, but hard to say exactly.

Thanks, I am going to re-install.

`--head` is not necessary since it's included in the latest release (0.1.46)

Fair enough (and thanks). I tend to run `--head` reflexively.

Thanks for that - you posted quicker than I could find the instructions on the documentation :D
