How to update gem to a version that's not the latest?

Ruby
1

I posted an earlier question but am amending it with this question
instead which hopefully gets to the heart of the matter:

I’m trying to get from rubygems version 0.9.5 to version 1.2.0 because I
believe that 1.3.0 has a possible bug. However when I install 0.9.5 and
then do a gem update --system it updates to 1.3.0 because that’s the
most recent in my remote repository (we use an internal repository,
btw).

The repository does have 1.2.0. How do I get to version 1.2.0 instead
of 1.3.0?

Thanks.

Download it manually and install from local file.

Thanks for the response, but the question of “how” was really the heart
of my question. I understand that gems can be installed locally by
using the -l switch, but when I try

gem update --system -l [some file name]

it does not work and I’m not clear on the difference between

gem install rubygems-update-0.9.5.gem

and

gem update --system

and

update_rubygems.

Am I the only person that finds this confusing?

Thanks.
