Git and Rails; How do I pass the PATH environment variable to script/plugin?

RoR People,

I'm trying to use script/plugin and git.

I see this error:

mac2:/pt/webprops/mmhq/mm12/mymoney maco$ ruby script/plugin install
git://github.com/activescaffold/active_scaffold.git
removing: /pt/webprops/mmhq/mm12/mymoney/vendor/plugins/
active_scaffold/.git
sh: line 1: git: command not found
mac2:/pt/webprops/mmhq/mm12/mymoney maco$
mac2:/pt/webprops/mmhq/mm12/mymoney maco$

How do I pass the PATH environment variable to script/plugin?

I want script/plugin to find my copy of the git executable.

Here is info about my RoR:
