GNUPG and PGP FreeWare 6.5.3

I was successfully able to do the following last night: First create keys in
gpg leave the password option empty. Then export the secret key using the
following:

 gpg --export-secret-keys --no-comment -a foo >foo.asc

Then open foo.asc in Windows PGP6.5.1 and change the password - this works.

>From here I have two choices in making the keys compatible: work out how to
change the password in GPG or import the PGP key pair back into GPG.

I was wondering if anyone knows if the RSA module in GPG will make any
difference to the exporting of secret keys?

Thanks, Oliver
