Hey guys, see my message below regarding a caching issue with the gem()
function. At this point, I just want to report the information I've
gathered regarding the specifics of the bug. I am willing to troubleshoot
this further, but to be honest, I'm not sure how to go about modifying the
rubygems library itself. Are there instructions for how to maintain your
own fork/branch of the library so that I can continue to troubleshoot the
issue?

Hey Chad, it looks to me like it's a problem in the rubygems API. The
Gem::SourceIndex class properly picks up on the newly installed gem, but the
call to gem() does not. But, there's a wrinkle. This only happens if a
call to gem for that gem previously failed.
*Scenario 1: Install gem before trying to activate it, then activate it with
success
*john-mbp:trunk john$ irb
>> Gem::SourceIndex.from_installed_gems.search("jtrupiano-sanitize_email")
:0:Warning: Gem::SourceIndex#search support for String patterns is
deprecated
=> []
>> `sudo gem install jtrupiano-sanitize_email`
=> "Successfully installed jtrupiano-sanitize_email-0.1.0\n1 gem
installed\nInstalling ri documentation for
jtrupiano-sanitize_email-0.1.0...\nInstalling RDoc documentation for
jtrupiano-sanitize_email-0.1.0...\n"
>> Gem::SourceIndex.from_installed_gems.search("jtrupiano-sanitize_email")
:0:Warning: Gem::SourceIndex#search support for String patterns is
deprecated
=> [#<Gem::Specification:0x112374c ........>]
>> gem 'jtrupiano-sanitize_email', '= 0.1.0'
=> true
*Scenario 2: Try to activate the gem before it's installed, then install it,
then try to activate again, and fail.
*john-mbp:trunk john$ sudo gem uninstall jtrupiano-sanitize_email
Successfully uninstalled jtrupiano-sanitize_email-0.1.0
john-mbp:trunk john$ irb
>> Gem::SourceIndex.from_installed_gems.search("jtrupiano-sanitize_email")
:0:Warning: Gem::SourceIndex#search support for String patterns is
deprecated
=> []
>> gem 'jtrupiano-sanitize_email', '= 0.1.0'
Gem::LoadError: Could not find RubyGem jtrupiano-sanitize_email (= 0.1.0)

So the caching issue appears to be further up the stack, specifically in the
rubygems library itself. I'm done looking into this for the evening, but
wanted to pass along my findings in the interim. I'm going to continue
working on this over the weekend.
