That is *definitely* not true. The code in
uses the *latest* version of a package; the basic loop goes like this:
package depends do: [ :depName |
"... some code omitted for brevity ..."
(universe hasPackageNamed: depName) ifTrue: [
packagesToConsider add: (universe newestPackageNamed: depName)
and #newestPackageNamed: does just what it says:
| potentials sorted |
potentials _ self packagesNamed: name.
sorted _ potentials asSortedCollection: [ :p1 :p2 | p1 version < p2

Given the above, how can it?
