Help: fpga-clear-local-image not found

I am following the HDK getting started guide, in particular I am trying to execute the " https://github.com/aws/aws-fpga/blob/master/hdk/README.md#how-to-create-an-amazon-fpga-image-afi-from-one-of-the-cl-examples-step-by-step-guide" for the hello world example.

I have successfully executed the first part - building the custom logic and publishing my new AFI. I have obtained the AFI ID and the AGFI ID. I have confirmed by executing aws ec2 describe-fpga-images my AFI is available and I have verified it is in the bucket.

The second part of the guide is about "how to load and test a registered AFI from withing an F1 instance".

I have created an f1.2xlarge instance using the Centos FPGA Developer AMI. The welcome message is

Now, the instructions read:

> git clone https://github.com/aws/aws-fpga.git $AWS_FPGA_REPO_DIR  
> cd $AWS_FPGA_REPO_DIR  
> source sdk_setup.sh  

(small aside: it would be best IMHO to provide the snipped with the definition of $AWS_FPGA_REPO_DIR again; the wording instructs to launch a new VM so I think definition cannot be assumed).

So far everything look ok.

I also ran aws configure as instructed.

OK.

Next step would be sudo fpga-clear-local-image -S 0

This is what happens in reality:

> \[centos@fpgadevc aws-fpga] sudo fpga-clear-local-image -S 0  
> sudo: fpga-clear-local-image: command not found  

Related FPGA commands don't seem to work either. I don't really know where to find them but I was more focused in going by the book for now. I have tried to understand why those commands don't work and I am so far out of clues. What did I miss?
