In our poky system, I saw we use some command to generate install_solution.manifest, and then use "rpm -Uvh" to install them. I attached my install_solution.manifest here. From the list we saw that some libraries are only installed once. For example the db, both 32bit and 64 bit are needed, however only 32bit is installed (libgtk is another example).
