New description:
Packages should be installed using `sage -i` from a shell, not with the
`install_package()` Sage command.

Comment:
I vote for removing the `install_package()` command. Installing packages
from within Sage can never work properly anyway:
1. for some packages, you need to rebuild the Sage library, which cannot
be done in Sage.
2. some packages might need a change in environment variables (e.g.
`ccache`) and that can only be done if `sage-env` is re-run after
installing the package.
