Redmine

Hi all,
sorry if i'm asking an already known issue, but i have googled a lot and i've not found a real soution.

Here the command that i'm trying to run:
ruby script/plugin --verbose install git://github.com/edavis10/redmine-bulk_time_entry_plugin.git -force

The answers is always:
Plugin not found: ["git://github.com/edavis10/redmine-bulk_time_entry_plugin.git"]
#<Errno::ENOENT: No such file or directory - /dev/null>

I tried all the possible combination with "http:" instead of "git:" and with a trailing slaah and without.
I also tried the fix proposed here for windows: http://groups.google.ca/group/rubyonrails-talk/browse_thread/thread/20cb12085cb7991e

In the meanwhile i will do:
cd vendor/plugins
git clone git://xxxxx.git

Is it fine?!?

Here some information on my system:

git --version
