First, one thing I didn't think of till now: If you are running the i386 version of Oneiric, you need to install the packages from here!:
Second, presuming you didn't install the "dbg" and "dev" packages beforehand, the only packages you need to install are:
Then, to install them you could of course try to use the Software Center, but I'd rather suggest GDebi for that, or the command line method:
Note: If you are using GDebi or the Software Center for that, you need to install the "bin" package first, as a matter of dependency!
sudo dpkg -i PACKAGE1 PACKAGE2
After that, lock their versions with Synaptic.
