I'm running Common Test from the command line using:
$ run_test -pa ../ebin -spec test.spec.all
and got the following error. Why does the io:format() call get a badarg error?

Are you sure you have something like ~s in io:format pattern ?
Can you provide some code that actually has this io:format ?
