-bash: /etc/profile.d/rvm.sh: No such file or directory
-bash: /Users/janekambani/.bash_profile: line 1: conditional binary operator expected
-bash: /Users/janekambani/.bash_profile: line 1: syntax error near `"$HOME/.rvm/scripts/rvm"'
-bash: /Users/janekambani/.bash_profile: line 1: `[[ -s "$HOME/.rvm/scripts/rvm"]] && . "$HOME/.rvm/scripts/rvm" '

Tentei o seguinte:

sudo rm -rf /etc/rvmrc /etc/profile.d/rvm.sh /usr/local/rvm /usr/local/bin/rvm $HOME/.rvm $HOME/.rvmrc

mas eu continuava recebendo o mesmo erro. estou usando o OS X 10.8
