This module requires DBFile, but that is standard with perl. It also requires MLDBM. This can be retrieved from any CPAN mirror site. To build and install the library by running these commands: perl Makefile.PL make make install ************************************************************* Please make sure that you have CDB_File version 0.86 or later ************************************************************* Please note, that CDB_File version 0.83 declares its self to have a version number 0.9. Since that version has a bug, I have put a check for that version number and CDB_File will die. N.B. in order to install CDB_File using the CPAN module you have to use the name TIMPX/CDB_File-0.86.tar.gz rather than just asking for CDB_File. Hopefully this will be fixed by the time you read this.
