The problem is that additional identities added to an RSA key by
PGP 6.5.8 are always v3 and not v4. You can't edit the v3
signatures in
GnuPG (assign primary status, preferences, etc).

But GnuPg creates v4 RSA keys. You have to do it in two stages,
a signing key first, theb "addkey" will give you some choices
which include "RSA encryption only".

This will then give you a key pair you can edit.
