# Also, disallow use of the map/reduce query links (i.e. /riak/bucket/key/_,_,_)

This example shows how to setup an environment running Rails 3 beta under 1.9.1 with a 'rails3' gem set.

∴ rvm update --head
# ((Open a new shell))

# If you do not already have the ruby interpreter installed, install it:
∴ rvm install 1.9.1

# Switch to 1.9.1
∴ rvm 1.9.1
