The library name has changed from liblept to libleptonica. So I have now changed the package name from liblept5 to libleptonica6. This is uploaded to experimental as leptonlib_1.84.1-3. I am including the revised Ben file below and attaching the patch for the most complex reverse dependency. All reverse dependencies have been examined, updated, and are ready for non-maintainer upload.
Ben file:
title = "leptonlib";
is_affected = .depends ~ "liblept5" | .depends ~ "libleptonica6";
is_good = .depends ~ "libleptonica6";
is_bad = .depends ~ "liblept5";
