My guess would be that this is about architecture differences.
What the install line from above indicates was installed on the 23rd is
the i386 version of liblilv-0-0. I suspect that the amd64 version was
already installed. The amd64 version of audacity depends on the amd64
version of this library, and the i386 version of audacity almost
certainly depends on the i386 version of this library.
Try
# aptitude purge liblilv-0-0:i386
and see what that gives you.
