libgdbm-compat4 1.23-1 (amd64 binary) in ubuntu kinetic

 GNU dbm ('gdbm') is a library of database functions that use extendible
 hashing and works similarly to the standard UNIX 'dbm' functions.
 .
 The basic use of 'gdbm' is to store key/data pairs in a data file, thus
 providing a persistent version of the 'dictionary' Abstract Data Type
 ('hash' to perl programmers).
 This package includes library files, required to run old programs,
 that use legacy 'dbm' interface. For new programs, please use modern
 interface, provided by libgdbm6 and libgdbm-dev.
