--no-site-packages?

According to the documentation, --no-site-packages will *not* copy the /usr/lib/python2.5/site-packages/* to the virtual env. So, when it is not specified, it should copy, right?

But, I see that the packages from my site-packages have not been copied into my virtualenv when created with something like:

virtualenv virtualenv-1.

Here is the content of my 'site-packages' in virtualenv:
