| This is a serious bug as it makes installation fail, and violates
| sections 7.6.1 and 10.1 of the policy. An optimal solution would
| consist in only one of the packages installing that file, and renaming
| or removing the file in the other package. Depending on the
| circumstances you might also consider Replace relations or file
| diversions. If the conflicting situation cannot be resolved then, as a
| last resort, the two packages have to declare a mutual
| Conflict. Please take into account that Replaces, Conflicts and
| diversions should only be used when packages provide different
| implementations for the same functionality.
|
| Here is a list of files that are known to be shared by both packages
| (according to the Contents file for sid/amd64, which may be
| slightly out of sync):
|
| /usr/lib/libQuantLib.so.0
| /usr/lib/libQuantLib.so.0.0.0
|
| This bug is assigned to both packages. If you, the maintainers of
| the two packages in question, have agreed on which of the packages will
| resolve the problem please reassign the bug to that package. You may
| also register in the BTS that the other package is affected by the bug.

Thanks [to your robot :-)] for catching that.
Quantlib used to just use one same filename, we now have libquantlib-1.0.0,
libquantlib-1.1, ... and I had simply forgotten to update the soname in
debian/rules. A new (and corrected) build will be forthcoming shortly.
