Package: libgsl23 Version: 2.5+dfsg-3 Severity: serious The 2.5 versions of this package introduced new symbols, but that isn't reflected in the shlibs file. It looks like this is caused by a simple typo: debian/libgsl23.shlib should be named debian/libgsl23.shlibs . So its contents aren't currently reflected in the binary package.
(This is showing up in the autopkgtest checks of the new libmath-gsl-perl package, which was built in sid against the new libgsl23 versions but didn't gain a corresponding versioned dependency, so it's installable but broken with the old libgsl23 in testing.) -- Niko Tyni nt...@debian.org
