fix type bug
remove activerecord

dear me from 3c6f5489d1df3a637d0905e65bde9269d36b1dbc

care to explain why zabbix needs activerecord? I’m sure that there
was a reason back then. If it was the puppet report I pulled then
that will need refactoring since getting rid of activerecord should
be less work than stabilising it in gentoo ;)
don’t install server on gentoo
unused local variables
use gentoo/portage module
