I'm foxed: why is Puppet complaining that it Could not find parent resource type 'mongodb::package::params' of type hostclass in production?

Found the error after dropping to puppetmasterd --debug --verbose --no-daemonize on the suggestion of the IRC channel:

debug: importing '/etc/puppet/modules/mongodb/manifests/package/params.pp' in environment production
err: Unclosed quote after '' in '7F0CEB10
}
' at /etc/puppet/modules/mongodb/manifests/package/params.pp:6 on node puppet.example.com
err: Unclosed quote after '' in '7F0CEB10
}
' at /etc/puppet/modules/mongodb/manifests/package/params.pp:6 on node puppet.example.com

The problem wasn't picked up by puppet parser validate.
