Ruby on Rails: 2.3.8: How do I get searchlogic to work with bundler?

Currently, I get this error: NameError: undefined methodmerge_joins' for class Class'

i'm just doing

gem "searchlogic"

and bundler says that it is using version 2.4.28

So... what in the right searchlogic version to use with rails 2.3.8?

searchlogic 2.4.28 was the last version available before it started requiring 2.3.11 =\

NameError: undefined method `merge_joins' for class `Class'

on line 16 in my env, I do this:

Bundler.require(:default)

EDIT: Gemfile:

source "http://rubygems.org"
# system
gem "rails", "2.3.8"
gem "activesupport", "2.3.8", :require => "active_support"
gem "rake", "0.8.7"

# might be for POW, not sure
gem "childprocess", "0.2.2", :git => "git://github.com/jarib/childprocess.git"


# app
gem "mysql", "2.7"
gem "lockfile"
gem "ssl_requirement", "0.1.0"
gem "attr_encrypted", "1.1.2"
gem "searchlogic", "2.3.5"
gem "will_paginate", "2.3.14"

gem "garb", "0.7.6"
gem "delayed_job", "2.0.3"
gem "httparty", "0.5.2"


gem "pony", "1.1"
gem "friendly_id", "3.0.6"
gem "stringex", "1.1.0"
gem "i18n", "0.4.2"

gem "sms_fu", "1.1.1"

It looks like 2.3.5 has decent Rails 2.3.x support:

gem "searchlogic", :version => "2.3.5"

Grepping through the history of the project shows the Rails 2.3.11 dependency was added in 2.4.29:

https://github.com/binarylogic/searchlogic/blob/v2.4.29/Gemfile

EDIT: Found some evidence on Heroku 2.3.5 will work with Rails 2.3.8, even though the dependency wasn't added until 2.4.28

As it turns out, the version(s) of searchlogic that I can use don't work with bundler, so I just kept this in my environment.rb:

config.gem "searchlogic", :version => "whatever"
