Looks fine to me.

I have libvorbis0_1.0rc3-1_i386.deb installed which includes:
-rw-r--r-- root/root 21292 2002-01-01 20:45:31 ./usr/lib/libvorbisfile.so.0.2.0
lrwxrwxrwx root/root 0 2002-01-01 20:45:30 ./usr/lib/libvorbisfile.so.0 -> libvorbisfile.so.0.2.0
libvorbisfile3_1.0.0-1_i386.deb replaces this
Conflicts: libvorbis0 (<< 1.0.0)
Replaces: libvorbis0 (<< 1.0.0)
but it contains libvorbisfile with a different SONAME
-rw-r--r-- root/root 22532 2002-07-19 10:45:51 ./usr/lib/libvorbisfile.so.3.0.0
lrwxrwxrwx root/root 0 2002-07-19 10:45:51 ./usr/lib/libvorbisfile.so.3 -> libvorbisfile.so.3.0.0
So when you upgrade to this version, all programs built with the previous
one don't find their libvorbisfile anymore. Or what don't I understand here?
Maybe all this will be fixed when I rebuild sdl-mixer with vorbis 1.0.0 (and
I don't have to rebuild defendguin for that?), but I want to be sure this
I still think the bug it with vorbis when it pulls away the library under my
legs, how am I supposed to know? Shouldn't it keep the old library around
until all packages that depend on it have been notified and updated?
