Those details influence whether the job is right, though. I won't work for a company that uses CVS, for example, because it tells me a lot about the culture of the company. They may have perfectly defensible reasons that make sense to them to use it, but I will, through my own cultural biases and feelings, not be comfortable there.
This is a bit extreme IMO. Tools should be a secondary concern for any developer. If a job is right for a person, such details should not matter.
