libmldbm-perl binary package in Ubuntu Xenial armhf

 The MLDBM perl module can be used to store multidimensional hash structures
 in tied hashes (including DBM files).
 .
 It depends on the Data::Dumper module and by default uses the
 SDBM tied hash. But you can use it with DB_File (and others
 DBM modules). You can also use other serializing packages
 like Storable and FreezeThaw.
