Don't you think the risk you are talking about in believing a 20 year old is exaggerated? Is it that hard to go back to the manager and ask if "Unix-like" is acceptable although the job description says "Unix"? Or just do a little bit of Googling to figure out if what the candidate is saying could have merit?
From my perspective, it appears that the recruiter is the jerk and not the candidate. I have met many computer-illiterate recruiters but never one like this who would repeat the same response over and over again despite the candidate having clarified his position.
