Load it from a workspace

Open a workspace and evaluate:

Metacello new
  repository: 'github://pharo-containers/BTree';
  baseline: 'BTree';
  load.

Load it from `BaselineOfYourProject`

I suggest you use your baseline: spec method and inside your version block code, call self btree: spec method consisting of:

  spec
  baseline: 'BTree'
  with: [ spec repository: 'github://pharo-containers/BTree/src' ]
