Geth client failure to load genesis block

after computing the genesis block:

Stefanos-MacBook-Pro:Ethereum stefano$ ls -l
total 2000
drwxr-xr-x 5 stefano staff 170 Aug 1 18:40 caches
-rw-r--r-- 1 stefano staff 1010850 Aug 1 18:41 genesis_block.json
-rw-r--r-- 1 stefano staff 10628 Aug 1 16:26 mk_genesis_block.py

I used instructions in

https://ethereum.org/cli

and invoked the following command

geth --genesis path/to/genesis.json console

This resulted in the following error message:

    clarification: the command I *actually* invoked was

    geth --genesis genesis_block.json console

    from the directory where the previously computed file

    genesis_block.son

    resides.
