   I'll reply in English so other people can correct me if I am wrong.
   I think unless you activate the expert options, you get a reduced set
of options. I added the line "expert" to my gpg.conf file, and I get the
following options when I generate keys:

Por favor seleccione tipo de clave deseado:
   (1) DSA y ElGamal (por defecto)
   (2) DSA (sólo firmar)
   (3) DSA (permite elegir capacidades)
   (5) RSA (sólo firmar)
   (7) RSA (permite elegir capacidades)
Su elección:

And the following options when adding a subkey.

Por favor seleccione tipo de clave deseado:
   (2) DSA (sólo firmar)
   (3) DSA (permite elegir capacidades)
   (4) ElGamal (sólo cifrar)
   (5) RSA (sólo firmar)
   (6) RSA (sólo cifrar)
   (7) RSA (permite elegir capacidades)

  The options you miss when generating a new key are the options where
you can chose the capabilities the key will have, and since a mistake
there can create a useless (for your purposes) key, they are available
only to experts (or to call them other way, to not-newbies).

  Best Regards
