The precise set of options I use for generating encrypted messages that
PGP2 will read is:

gpg --no-options --batch --load-extension rsa --no-default-keyring
--keyring [foo] --output - --quiet --always-trust --armor -r 0x[to
keyfingerprint] --rfc1991 --load-extension idea --cipher-algo
idea --encrypt foo.txt > output

It is critical that you ecrypt a file given on the command line not using
a pipe. GPG uses a different packet format that PGP 2.x will not read.

The reason the above disables the option files and such is that it is part
of a more complex script, I suggest using it as a starting point and then
going on to putting it in config files.

--- Example #1 ------
Wakko{jgg}~/work/ldap/userdir-ldap#gpg --no-options --batch
--load-extension rsa --no-default-keyring 
--keyring ~/.pgp/pubring.pgp --output - --quiet --always-trust --armor -r
jgg --rfc1991 --load-extension idea --cipher-algo idea --encrypt
markers.dat > jnk

You need a pass phrase to unlock your RSA secret key. 
Key for user ID: Jason Gunthorpe <jgg@gpu.srv.ualberta.ca>
1024-bit key, key ID 35261E21, created 1997/09/08

Enter pass phrase: 

Output file 'markers.dat' already exists.  Overwrite (y/N)? y
