stdlib module in puppet usage

[LaksThampi]

Trying to use the stdlib class to use the file_line resource
class postgresql::profilechange1{
include stdlib
file_line{'Path updation':
ensure => present,
line => 'PATH=$PATH:/usr/local/pgsql/bin\n',
path => '/etc/profile',
}
}

---

Error encountered
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class stdlib for sys-server on node sys-server
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

Is unable to find the class stdlib to use the file_line class?
What needs to be there other than the class installed
I have puppet 3.4 installed
