Thanks for your replies. The Crypt::CBC on the old server was 2.02, with Crypt::IDEA 1.01. On the new server I have Crypt::CBC 2.08 installed and Crypt::IDEA 1.02. I did try to "downgrade" both modules on the new server, and the CBC compiled OK but i get errors with the older IDEA: 
[root@ Crypt-IDEA-1.01]# perl Makefile.PL
Checking if your kit is complete...
Looks good

I agree it would be ideal to have the newer modules running on both servers -- I am just not sure the best way to ensure backward compatibility with data that is stored encrypted via the "old method". I guess I could create a copy of the table in question with unencrypted data, and then re-encrypt with the new method. Any other suggestions?
