RubyMine (EAP) not detecting RVM ruby

Hi. I've just freshly installed Ubuntu 10.04. I skipped installing the system ruby and instead just installed RVM. RubyMine (EAP version) is not detecting any installed ruby SDK. It won't let me manually specify the location either, giving the message "Error configuring SDK: null. Please make sure that /home/jeremy/.rvm/rubies/ree-1.8.7-2010.01/bin/ruby is a valid home path for this SDK type."

Output of which ruby: /home/jeremy/.rvm/rubies/ree-1.8.7-2010.01/bin/ruby
