Need help with require while modifiying a gem (active_merchant)

I'm trying to add a new gateway to the active_merchant gem and I'm having 'require' issues when I try to run it from source.

(I think my problem is not active_merchant-specific, but more of a general Ruby environment issue, so I dont think the specific gem in use has to do with it.)

This is what I've done:

1. Cloned the Git repo for AM, to my local directory "C:\Users\jb\Documents\Aptana Studio 3 Workspace\active_merchant"

2. Went about doing the changes in the "billing/gateways" directory (this is just background info..)

3. Copied the "Sample Usage" example on AM's Git repo to C:\Users\jb\Documents\Aptana Studio 3 Workspace\simple_gw_test.rb, which starts with:

   require 'rubygems'

   require 'active_merchant'

4. Ran "ruby simple_gw_test.rb" and got the error message:

   <internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- active_merchant (LoadError) from <internal:lib/rubygems/custom_require>:29:in 'require' from simple_gw_test.rb:3:in '<main>'

This is understandable, since I don't have active_merchant gem installed

However, I want to use the downloaded source in the sample file, since I'm modifying the gateway source continually.

I tried

require '/Users/jb/Documents/Aptana Studio 3 Workspace/active_merchant'

And then got the same error:

<internal:lib/rubygems/custom_require>:29:in require': no such file to load -- /Users/jb/Documents/Aptana Studio 3 Works开发者_JAVA技巧pace/active_merchant (LoadError) from &lt;internal:lib/rubygems/custom_require&gt;:29:inrequire' from simple_gw_test.rb:2:in `<main>';

Any Ruby Guru who can shed some light greatly appreaciated!

PS: I'm using MRI 1.9.2 on Windows 7 x64.

Make sure you have read access to that file. Ruby has given me that error before when I didn't have correct permissions.

I guess I scratched my own itch: After a couple of hours of "Pickaxe book-ing" and googling, I got the code necessary to bootstap the gem without it being installed:

require_relative 'active_merchant/lib/active_merchant'
