Currently, my rvm based projects specify rvm 1.8.7@gemset in .rvmrc. This means that when I am installing the gemset of a new project, it will default to the latest patch level of 1.8.7, eg. ruby-1.8.7-p352 . Now I don't want to hard code '1.8.7-p352' in the rvmrc as other developers(or other projects) might have some other patch levels installed on their machine(from other projects) and also I don't want to install different patch levels of ruby on my machine.
Is there a way to make rvm ignore the patch level and just make it use any version of 1.8.7 installed - so that I can use one patchlevel of Ruby 1.8.7 across all projects.

Ruby Version Manager (RVM) is a utility that allows you to add your own personal version of Ruby to a user. It allows you to add, remove, or have multiple versions of Ruby and its libraries live in your user directory.
RVM is easier to install than Rbenv, RVM has more features than Rbenv, RVM includes a built-in Ruby installation mechanism while Rbenv does not.
To set a default Ruby version with rvm, enter rvm --default use 3.0. 0 on the command line. To switch to the system ruby, enter rvm use system . To switch back to the default, rvm default .
0-p481 is the latest, RVM will attempt to download, install, and set 2.0. 0-p481 as your default 2.0.
The thing you want to set up is called an rvm alias. See: http://rvm.io/rubies/alias
For your example the commands would be:
rvm alias create 1.8.7 ruby-1.8.7-p352
