Well now, that is new information to me, that you are not using the current firmware.
If you do switch to the current firmware, you can use LibrarianSync for your collections.
And of course, Amazon has since CM introduced maintaining your collection in the "manage devices and content" web page of your account.

PS: The LDD script is just looking at the system cache - which I don't recall you mentioning that you had updated, that you where using LD_LIBRARY_* features.
Use readelf and/or objdump (+ grep as required) to find out what the binaries contain and require.
Not what Amazon's cache thinks you want.
