Ruby on Rails

hi, i had rvm system wide, but then switched to a user installation, and now im getting this:

 cap production deploy

DEBUG [18852256] Running /usr/bin/env which passenger as administrator@domain.com

DEBUG [18852256] Command: ( export RVM_BIN_PATH="~/.rvm/bin" ; /usr/bin/env which passenger )

cap aborted!

SSHKit::Runner::ExecuteError: Exception while executing as administrator@domain.com: rvm exit status: 127

rvm stdout: bash: /usr/local/rvm/bin/rvm: No such file or directory

rvm stderr: Nothing written

SSHKit::Command::Failed: rvm exit status: 127

rvm stdout: bash: /usr/local/rvm/bin/rvm: No such file or directory

rvm stderr: Nothing written

this is how my deploy.rb starts

require "rvm/capistrano" # Load RVM's capistrano plugin.

set :user, "administrator"

set :rvm_bin_path, "$HOME/.rvm/bin"

set :default_env, { rvm_bin_path: '~/.rvm/bin' }

set :rvm_type, :user

any ideas?

thx
