I'm not so sure : harder to do, harder to understand, not obvious at reading the spkg-install script. But cleaner, indeed.
Plus, it allows for explicit installation if you want to install it anyway. It's nice for example that `./sage -i gcc` does install gcc, regardless of whether you need it or not.
If the check would be in the spkg-install script of curl, then `./sage -i curl` would *not* install curl.
