Oh, what a happy little mistake! Let's gently correct that sentence by saying, "She yelled to warn him, but it was too late."

No, the verb is incorrect. The subject is 'one', a singular form. The correct sentence is, "Not one of the girls was late." "Of the girls" is a prepositional phrase. The actual sentence is "One was late." However, in modern American usage, the use of the term girls to clarify the indefinite pronoun one makes the term "one" to be taken as plural. That and the poetry of the sentence overrides the traditional grammar. So, in modern American English, it is acceptable to say, "Not one of the girls were late."
