Due FreeBSD port's executables installed to /usr/local by default, puppet's default path-es to executables have to be changed to /usr/local/bin/ instead of default /usr/bin
(and default root dir for svcscan is /var/service, not /service)


without changes puppet generate an error when we try to use service{ provider => daemontools;}
Debug: Puppet::Type::Service::ProviderDaemontools: file /usr/bin/svc does not exist
 Provider daemontools is not functional on this host


next patch fix the problem
