Weird!

ebdb-pgp.el, ebdb-org.el and ebdb-gnus.el all have autoload cookies on
`defclass' forms. You've already got Gnus required (naturally), but the
other autoloads are causing the evaluation of the forms without
requiring the library that provides the parent classes.

At least, that's what my crystal ball says! Both ebdb-pgp.el and
ebdb-org.el require ebdb-com, which in turn requires ebdb.el, which is
where ebdb-field-user is defined. But that somehow isn't getting pulled
in for the native compilation (?).

It's also very likely that we're not supposed to be using autoload
cookies on defclass forms at all...
