[Glass] Metacello question

[Jupiter Jones via Glass]

I have a baseline that will support squeak, pharo, and gemstone.

The gemstone one I get, but how to load a specific version of a package from a squeak source repo?

spec
    for: #’squeak'
    do: [ 
      spec
        package:  'Cryptography'
        with: [ 
          spec
            file: 'Cryptography-zzz.111.mcz';
            repository: 'http://www.squeaksource.com/Cryptography' ] ].

  spec
    for: #'gemstone'
    do: [ 
      spec
        baseline: 'Cryptography'
        with: [ 
          spec
            loads: #('CI');
            repository: 'github://GsDevKit/Cryptography:master/repository' ] ]

I’ve been looking for an example in the many BaselineOf but couldn’t find an example that specifies the package, version and repository.

Cheers,

J
