I suspect you're missing 'l' off the end of "local"
It should be
program => '/usr/local/bin/starman',
rather than
program => '/usr/loca/bin/starman',

Amelia and Andrew,
Thank you for pointing out my errors. I was so focused on my ignorance that I overlooked carelessness. After correcting the typos it now works. Thank you also Gabor for putting together a fine tutorial.
