you are not saving the image after eval:

./pharo Pharo.image eval --save ���
�� �� �� �� Metacello new
�� �� �� �� �� �� �� �� baseline: #YourTribes;
�� �� �� �� �� �� �� �� repository: 'github://HappyPharoHackers/YourTribes';
�� �� �� �� �� �� �� �� load: #(tests)"

(also your line has a syntax error but I suppose that���s a transcription error)
