If it's a Rails 2.x.x app, there's probably going to be a line near the top
of config/environment.rb like:
RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION

You can also use the commands `rails -v`, `ruby -v`, `gem list`, and
`gem env` to explore the original environment.

Having recently gone through this with an app I didn't write, I'd suggest
(assuming it's not under any source control)

1) tar up the whole thing and untar it on your system
2) create a git repo and commit the app as-is
3) try to run the tests and/or run the app locally; if anything's missing
on your system that the app needs, you'll know quickly enough. :-)
4) this may be a good point to set up a separate gemset, if you're using
rvm locally.

If the original system and your system are different architectures,
you might have to un-vendor gems with native code.

Good luck!
