Configuring issue when install a version of Ruby with RVM

RVM is installed and running. I am trying to install Ruby 2.0, but this happens with any version I try to install. This is a fresh install of rvm without ruby. I am running Debian Squeeze. After running ``` rvm install 2.0 ``` I get this error: ``` Installing Ruby from source to: /home/user/.rvm/rubies/ruby-2.0.0-p0, this may take a while depending on your cpu(s)... ruby-2.0.0-p0 - #downloading ruby-2.0.0-p0, this may take a while depending on your connection... ruby-2.0.0-p0 - #extracted to /home/user/.rvm/src/ruby-2.0.0-p0 (already extracted) ruby-2.0.0-p0 - #configuring...................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
