I believe there are two ways to handle dependances: either you bundle
your dependances with your package (they just live in a directory
inside your package, you don't install them) or you leave resolution of
dependances to the application that uses your package. Handling
dependances like you do it (package installs other packages) doesn't
seem like a good idea to me.
