Need advice... went on interview

I applied for a local job as a computer specialist position that begins January 1, 2009 due to construction of their new facility.

I went on the job interview last month, October 8 to be exact, and everything seemed to go great. The IS manager asked questions and I answered them well, in my opinion. The interview itself lasted about 70 minutes. They seemed very interested as they walked me to the door showing me the location for their new office building and heliport. I also asked them about the followup timeframe. He told me if I didn't receive a call from him in 2 weeks to give him a call.

Let's fast forward 2 weeks to October 24, 2008. I give him a call and do the followup call. He sounds very enthused that I called and states he wants to speak with me more about the job and if I can start earlier than January. He told me he wanted to call me "next week". It's 7 business days later and I have yet to hear from him. Would it be best to call him again? If so, what should I say? I don't want to become a nuisance, but this is a job opportunity that I think I can excell at and really enjoy the job.

It is becoming depressing :shrug:
