This should:

1) use #subStrings: or alternatively a single regex match

    ^(\d+)\.(\d+)(?:\.(\d+))$

instead of tokenize.

2) be in Version class>>#fromString:

3) accept a version like 1.0 and change it to 1.0.0 (see regex above).

Otherwise looks fine, filtering of prerequisites based on their version 
can be done later.
