OK, so I just nipped across the border to Belgium to get the 
extension. But it still doesn't work:

$ gpg -vv test.txt.pgp
gpg: Warning: using insecure memory!
:encrypted data packet:
        length: 45
gpg: loaded digest 3
gpg: /home/mark/.gnupg/idea: IDEA ($Revision: 1.11 $)
gpg: BLOWFISH encrypted data
gpg: decryption failed: bad key

(the test file is attached to my previous message to the list)

If I follow your instructions completely the result is still bad:

$ gpg --load-extension .gnupg/idea  --cipher-algo idea -vv \
 	test.txt.pgp
gpg: Warning: using insecure memory!
gpg: .gnupg/idea: IDEA ($Revision: 1.11 $)
gpg: loaded cipher 1 (IDEA)
gpg: /home/mark/.gnupg/idea: IDEA ($Revision: 1.11 $)
gpg: skipping cipher 1: already loaded
:encrypted data packet:
        length: 45
gpg: loaded digest 3
gpg: IDEA encrypted data
gpg: decryption failed: bad key


Thanks,
