Sorry if i was not clear enough. No, the command doesnt fail. And when
i list the roles,  newroleX is there:

(pyenv)ruben at ruben-laptop:~/pyenv/src/ckan$ paster --plugin=ckan roles list
newroleX            create-package, read-site, read
editor              read-site, read-user, create-user, edit,
create-package, create-group, create-authorization-group, read
anon_editor         edit, create-package, read-user, read-site, read
reader              read-site, read-user, read

I just meant i expected a direct way of creating the role (not
indirectly, assigning it actions). And thats all because when i try
now to use that new role newroleX, 'rigths' command does not recognize
it:

(pyenv)ruben at ruben-laptop:~/pyenv/src/ckan$ paster --plugin=ckan
rights make agroup:ibiasgrupo newroleX group:ibias
No handlers could be found for logger "vdm"

    role = self.ensure_role(unicode(role))

    ", ".join(roles))

Yes, you are right. Just thought the command allowed you to specify
several actions. But no, you have to do it one by one.
