compass_twitter_bootstrap different path

hi everybody,
i'm working on an app based on rails 3.2.6.
for a particular reason i have to install all the gems in a local folder inside the app (vendor/gems/folder_name)
i've install compass_twitter_bootstrap successfully but when i try to import the stylesheet (@import 'compass_twitter_bootstrap') i receive this error:

File to import not found or unreadable: compass_twitter_bootstrap.

it seems a path issue. i've tried to add the folder into the config.assets.paths but nothing seems to work.

any tips?
