libbind-dev 1:9.9.3.dfsg.P2-4ubuntu1 (i386 binary) in ubuntu saucy

 This package delivers archive-style libraries, header files, and API man
 pages for libbind, libdns, libisc, and liblwres. These are only needed
 if you want to compile other packages that need more nameserver API than the
 resolver code provided in libc.
