Making it simple

Perhaps nothing.  If the encrypted data will be encrypted to your
keys, then GnuPG 1.0.7 allows you to select your preference
of encryption algorithms.  PGP 6.x or 7.x will encrypt to the
preferred algorithms on your key.  GnuPG will decrypt this 
data OK.  Thank you, OpenPGP Foundation.

Of course, if you created your keys on PGP, the preferred
algorithm on the key will be "idea".  You can export a key
like this from PGP to GnuPG and be able to send messages
one way only -- from GnuPG to PGP.  PGP will encrypt to
your "idea" preference, and you'll need to add "idea" to
your GnuPG installation to be able to decrypt.

But if you change the key preferences from "idea" to, say, 
AES, then "gpg -a --export <key>" the public key back to PGP,
then PGP will start encrypting keys to AES.  Interoperability
restored.  Send the public key to the keyserver and everyone
with fairly up-to-date software revisions will be able to find
out which algorithm you prefer.
