You seem to miss the basic understanding in installing applications.
The additional libraries are hidden in HildonApplicationManager (HAM) totally and hidden in FasterApplicationManager (FAM) by default. You could make them visible in FAM in the categories view, but to install any application will pull the dependency libraries automatically in both managing apps.
Because pure command-line tool apt-get will pull in those libraries, which those manager use in the background.

If you try to manually install packages, you must not use any file manager by clicking(tapping) at the icon of the downloaded .deb package, but use the X-Terminal application, gain root rights via some packages, that allow you to, and use dpkg command-line tool.

Long story(sorry for the bla,bla),short: Your repository setting seem to be incorrect. You could post it here for others to check. Please paste the output of the terminal command
