How do you figure?  As far as I remember, both the GPL and LGPL only kick in
once you distributed your software.  I can do whatever I want to vorbis, but
as soon as I "distribute" (ex: release a program that uses the library) it to
another person, I have to do it in a way that conforms to the LGPL.

The GPL requires nothing of private copies.  It's just that private copies are
only of limited utility to a programmer.
