Prediction.io: Unable to deploy engine

I'm trying to set up a Prediction.io Text-Classification Engine on my local machine. However, upon attempting to pio build, I get the following message:

[ERROR] [Console$] No valid engine instance found for engine iMXSzwtuLBqTGDQVWFwhXLyX3MELx6Ox 2089ace31214efdc353ab45e911b7524222d7ab6.
Try running 'train' before 'deploy'. Aborting.

As specified in the tutorial, I've already imported the sample data. I'm able to build and train the engine without any issues. Any ideas why it's unable to find a valid engine instance?

Relevant Information:

The last line in your pio train is the cause:

/usr/local/Cellar/predictionio/0.9.5/libexec/conf/pio-env.sh: line 55: PIO_STORAGE_SOURCES_PGSQL_PASSWORD: command not found

Have you setup the password for your PostgreSQL and put it in pio-env.sh? If that doesn't help, feel free to pastebin your pio-env.sh (edit out passwords etc of course)

If you have further questions along the way, post it to PredictionIO's Google Group where your question will be answered more quickly by our community.
