Installing Package Dependencies

[magnadd]

I know to search at http://packages.ubuntu.com/ if I want to find a package to install. However, there are usually lots of dependencies (given by red circles) which have even MORE dependencies for each of them. Is there a way to download and install them all at once?

Allow the package manager (i.e. aptitude, apt-get, Synaptic, Add/Remove, etc.) to handle it.
