Just to close this issue, the problem with the neutron-dhcp-agent was not the dnsmasq
version but SELinux policies. The command 'setenforce 0' seems to have fixed the
problem and the agent started normally.
Should I open a bug about this (because it seems that some policies have not been set
correctly)?
Thank you,

 That's known bug on F19 . Previous version of installer gave
packages conflict and failed,
  what is actually much better then it happens in meantime.
 
    New version completes OK, but service openstack-horizon  shows up status 500.
 Dashboard doesn't work.

 Please, run 
 
 # rpm -qa | grep python-django 
 Sure:
 
 [root@openstack ~(keystone_admin)]# rpm -qa | grep python-django 
 python-django-appconf-0.6-1.fc19.noarch
 python-django-1.5.4-1.fc19.noarch
 python-django-openstack-auth-1.1.2-1.fc21.noarch
 python-django-compressor-1.3-1.fc19.noarch
 python-django-horizon-2013.2-1.fc20.noarch

 Uninstalling python-django and re-running packstack seems to have worked. Thank you very
much!
