Summary: Activating a dependency raises error even though a satisfactory
version is already activated.
Initial Comment:
I have loaded a gem "A" that loaded version 0.9.13 of gem "B", and then
continued to load gem "C" that needed version "~> 0.9.12" of gem "B". Under
normal conditions, version 0.9.13 should suit just fine if I'm looking for "~>
0.9.12".
But in this case, since:
(1) version 0.9.13 is *already loaded*, and
(2) I have since changed my Gem path in such a way that 0.9.13 is not able to
be found in the new Gem path,
-> it fails and raises an error saying that it can't activate.
This happens because in rubygems.rb, line 268:
unless matches.any? { |spec| spec.version == existing_spec.version } then
This should look at the existing spec and test whether it passes the
version-requirements. However, the way it is doing it depends on the
already-loaded spec to be able to be found again in the most recent search.
This fails if the Gem paths have changed and the already-loaded spec is a
version that is no longer able to be found in the new Gem path.
This proposed change to this single line fixes the problem:
rubygems...@268
- unless matches.any? { |spec| spec.version == existing_spec.version } then
+ unless gem.version_requirements.satisfied_by?(existing_spec.version) then

Please respond to Eric's question so I can write a failing test.

Do you have a set of gems that can reproduce this?
