eycap v0.6.8 fails to detect rvm gem path with rvm-capistrano v1.4.3

After upgrading to rvm-capistrano v1.4.3 in my Engine Yard Managed environment, my app's gems are now getting installed in `/data/app_name/shared/bundled_gems/ruby/1.9.1/gems` instead of in `/usr/local/rvm/gems/ruby-1.9.3-p429@app_name/gems/`.
