Hi Charles. We need to be clear in something: indeed, there are too many things to install.
So....you can use Installer or Gofer to script your installation in code, but you can still use the normal Monticello Browser.
Installer is not loaded in Pharo, so I suggest:
a) Use Monticello Browser: open it, new repository -> MetacelloRepository, you search ConfigurationOfDesigner, select it, and then load.
Just like lading any other monticello package.
Easy.
b) Script it. With Gofer, you can do:
Gofer new
repository: '
http://www.hpi.uni-potsdam.de/hirschfeld/squeaksource/MetacelloRepository';
package: 'ConfigurationOfDesigner';
load.
Once you did a) or b) evaluate: ConfigurationOfDesigner load.
Cheers
Mariano
