Debian squeezeの、gnomeターミナルで、rvm useがエラーになってしまう。

indou@cf-t8:~$ rvm list

rvm rubies

ruby-1.9.3-p392 [ x86_64 ]

indou@cf-t8:~$ rvm use 1.9.3

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

indou@cf-t8:~$

再度gnomeターミナルを再起動して、

indou@cf-t8:~$ rvm list

rvm rubies
