[ruby-core:31005] Re: [Bug #3140] gem activation has changed between 1.8 and 1.9

We are about to ship a version of Ruby with a built in package manager with
the following property:

Given a package X with dependency Y, attempting to load X might require
dependency Z without any warning.

There is literally no other distribution of anything that would not consider
that property a major show-stopper. I am baffled about how this bug has
existed in the tracker so long, is considered "normal" priority, and has now
been bumped to 1.9.3 at the earliest.
