how to install plone.app.event on a policy package?

hi, I'm finishing integration of p.a.event 1.1.1 on a policy package for 
a project I'm working on;

- I listed it as a dependency on setup.py

     install_requires=[
         ...
         'plone.app.event [archetypes] <1.2',
         ...
     ],

- I read its configure.zcml:

     <include package="plone.app.event" />

- I installed it adding the following to metadata.xml:

     <dependency>profile-plone.app.event.at:default</dependency>

the package installs its configlet because I see a link to Event 
Settings on the control panel:

https://github.com/plone/plone.app.event/blob/1.1.x/plone/app/event/profiles/default/controlpanel.xml

but both GS profiles appear as not installed.

also, a quick test show it is not installed indeed and can not be installed:

(Pdb) self.qi.isProductInstalled('plone.app.event')
False
(Pdb) from plone import api
(Pdb) setup = api.portal.get_tool('portal_setup')
(Pdb) 
setup.runAllImportStepsFromProfile('profile-plone.app.event.at:default')
     ...
(Pdb) self.qi.isProductInstalled('plone.app.event')
False

if I install plone.app.event.at via control panel it seems to work, but 
then plone.app.event 1.1.1 remains uninstalled.

what I'm doing wrong? do I have to deal manually with 
Products.DateRecurringIndex dependency in some way? do I have to install 
plone.app.event before plone.app.event.at? how?

best regards
