Can someone suggest any online venues to assist in recruiting a senior C programmer (looking for someone interested in working on kerberos code).

I've tried a bunch of the open source and higher ed lists (this is for Univ. of Michigan). The commercial services such as Dice or monster yield a ton of resumes without any programming experience.

Please note I'm NOT a recruiter or a solictor (not violating rule #7) and I'm not ACTUALLY asking folks to contact me about a job (or giving any significant deal on the job). I'm just asking where to post the find people like that.
