check them in pgp dump:


in order to generate a key from gnupg that will be compatible in pgp
2.x,

it is necessary to use the following additional options in gnupg, besides
the ones you used:

--simple-s2k-checksum
--s2k-mode 0 
--s2k-cipher-algo idea 

[n.b. there is 'no' dash between mode and 0 and between algo and idea
]

if these options are not used, then gnupg will use its defaults, which
will be to salt and iterate the passphrase for secret key protection,

and also use cast5 instead of idea to protect the secret key
(and these will not work in pgp 2.x )

the following keypair was generated in gnupg with the above options and
imports and works well in pgp 2.x
