Clear now, thanks...

Now, when I try to remove liblilv-0-0, Debian warns me that audacity depends on
it:

# aptitude purge liblilv-0-0
The following packages will be REMOVED:  
  liblilv-0-0{p} 
0 packages upgraded, 0 newly installed, 1 to remove and 192 not upgraded.
Need to get 0 B of archives. After unpacking 132 kB will be freed.
The following packages have unmet dependencies:
 audacity : Depends: liblilv-0-0 (>= 0.16.0~dfsg0) but it is not going to be
 installed


But audacity is installed on my Debian box since months...  How can it depend
on a package installed a few days ago...?
