This module requires DBFile, but that is standard with perl. In order to work you have to have "cdbmake" installed (part of the CDB distribution which is included in the CDB_File source distribution if nowhere else). The tests require CDB_File and so do your applications probably. This can be retrieved from any CPAN mirror site. To build and install the library by running these commands: perl Makefile.PL make make test make install
