I added #error ooops on line 102 in the specified file. Compilation  
passed without any errors.

Yes, all 27 tests pass.

Done, encryption/decryption works fine when I generated new keys  
without moving them to the card.

I tried to create the keys the same way as when I generated them for  
the card, that is, I also removed the main key's secret key from my  
keyring. (Following this guide: https://we.riseup.net/debian/using-the-openpgp-card-with-subkeys 
  ).

I have "hidden-encrypt-to" specified in my gpg.conf, with the key-id  
of the encryption subkey.

Unfortunatly I only have one Mac, newly formatted to Snow Leopard, so  
I'm afraid I can't test it on any other version.
