Can't install Gulp

Hi all ! On Yosemite I have nodejs version 0.10.31 and npm version 1.4.23

When I run :

sudo npm install -g gulp

I have this message :

/usr/local/bin/gulp -> /usr/local/lib/node_modules/gulp/bin/gulp.js

Now if I check gulp I have this instead of the Gulp version :

[17:48:40] CLI version 3.8.7
[17:48:40] Local version 3.8.7

Could you tell me what's going wrong ?
