Hi, Many of packages include bundled Aladdin Enterprises independent implementation of md5. Full list can be seen at https://codesearch.debian.net/search?q=typedef+unsigned+char+md5_byte_t&perpkg=1 (100 packages)
As discussed in #909116, libmd-dev now provides a compatible interface for that, so bundled sources should be dropped. A potential fix for that might be replace the md5.h header with #define LIBMD_MD5_ALADDIN #include <md5.h> remove building for md5.c, and add Build-Depends: libmd-dev (>= 1.0.1) Thanks,
