How Do I Read An Old DB File?

shachter has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to read an aliases.db file that was, apparently, created by an old sendmail program. The “file” command reports:

Berkeley DB (Hash, version 5, native byte-order)

and this is, apparently, too old for DB_File to read. I have another aliases.db on another computer which is (according to the “file” command)

Berkeley DB (Hash, version 9, native byte-order)

and DB_File reads that one perfectly, so there is nothing wrong with my perl program. Lest you be tempted to tell me to use a more modern DB format for my aliases.db file, I tried that already, and it didn't work. I ran newaliases on my new computer, and sent the newly-generated aliases.db file back to my old computer, and my sendmail program on my old computer couldn't read it, so it was useless. I have to use the version-5 format. How do I write a perl program that can read it? If you do not think that this question is of general interest, please do me the kindness of replying to me at
