The following script should work:

Gofer new
� � �url: 'http://www.smalltalkhub.com/mc/Moose/GToolkit/main';
� � �configuration;
� � �load.
(Smalltalk globals at: #ConfigurationOfGToolkit) loadDevelopment
(Smalltalk globals at: #GTInspector) registerToolsOn: Smalltalk tools.
(Smalltalk globals at: #GTPlayground) registerToolsOn: Smalltalk tools.

Moose is installable as any other software. The reason for having a Moose image is essentially due to the long time taken by moose to be loaded.
In addition, the moose image comes with a theme.
