i just downloaded the image from pharo-project web site today. it is called 1.0 RC3. my installation process is;
1-open monticello browser and browse MetacelloRepository.
2-load the configuration package. (ConfigurationOfO2 for this situation)
3-eval the load like method. for O2 i evaluated:
(Smalltalk at: #ConfigurationOfO2) loadDefault.
i am installing my all other tools like this.
But that's not what you want. That's why I told you to install it in this way:
Gofer new
squeaksource: 'MetacelloRepository';
package:'ConfigurationOfO2';
load.
((Smalltalk at: #ConfigurationOfO2) project
version: '1.2') load: 'Dev'.
In metacello you can define groups of packages. When you load something with Metacello, you can do just load and that will load the default packages. But after, you can have differents groups. The default can be just the core packages. Then you can have groups called "Dev" where it also installs the dev tools.
Using load: you specify a group name, a package name or a list.
Take a look at the class ConfigurationOfO2, to the baseline methods, at the end, where the groups are defined.
Moreover, I recommend you to read the Metacello tutorial:
