deployment of a functioning contract (testrpc) to ropsten with truffle/geth

Question

I've developed a smart contract using truffle and testrpc, which can be found on GitHub here.

At this point I want to deploy it to ropsten, but I can't figure out how to do that.

After consulting this question/answer, I attempted to concoct a deployment for my smart contract as follows:

module.exports = {
  networks: {
    localhost: {
      host: "localhost", 
      port: 8546, // for ropsten expose this one
      //port: 8545, // expose this one for testrpc
      network_id: "*" // Match any network id
    },  
// for ropsten uncomment all of this
// for testrpc comment it all out
    ropsten: {
      host: "localhost",
      port: 8545,
      network_id: "3"
    }
  }
};

and here's how I tried to execute the deployment:

> truffle migrate --network ropsten

Using network 'ropsten'.

Running migration: 1_initial_migration.js
    Deploying Migrations...
    ... undefined
Error encountered, bailing. Network state unknown. Review successful transactions manually.
Error: exceeds block gas limit

This is a screenshot of the full terminal output:

My question is, how can I deploy this simple contract to ropsten?

EDIT:

Found this:

but it didn't seem to help, i.e. still getting an error:

The part of the error message that you need to pay attention to is the:

Error: exceeds block gas limit

you can fix that by modifying you truffle.js to contain the line gas: 500000 like so:

module.exports = {
  networks: {
    localhost: {
      host: "localhost", 
      port: 8546, // for ropsten expose this one
      //port: 8545, // expose this one for testrpc
      network_id: "*" // Match any network id
    },  
    ropsten: {
      host: "localhost",
      port: 8545,
      network_id: "3",
      gas: 500000
    }
  }
};

then deploy it like this:

truffle migrate --network ropsten --reset

and for me that seemed to work, as you can see here:
