Terminal ~ / .profile non contiene 'source ~ / .bashrc' in OS X 10.9.1

Il terminale viene mostrato di seguito in questa fase sulla pagina di installazione di gerris: link

Note: make sure that the file ~/.profile contains the line
source ~/.bashrc

Ma ~ / .profile non contiene source ~ / .bashrc. Come posso gestirlo?

GNU nano 2.0.6        File: /Users/samirebalta/.profile
