One could specify a different file to download. It wont find the file on a
Gentoo mirror and will download it from where it is specified in the
ebuild. Also I could care less if it actually downloads the real file. The
ebuild could patch the code or do many other things. The ebuilds,
packages, and patches need to be signed in some way. Then you just have to
trust the developers and that no keys get stolen. Or you can check
everything before you install something.
