libgdbm-compat4 1.18.1-5.1 (armhf binary) in ubuntu groovy

 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.
