To search for a file in currently installed packages use: 
dpkg -S filename

To search in all packages use:
apt-file update; apt-get search filename

apt-cache does generally not help for finding a file, since it only has
package descriptions to search.

Remember a 32bit program requires the 32bit version of the library.
This is why many people use a chroot to manage 32 bit versions of files.
