[doug-a-brunner]

I ran into this same problem; the cause was incompatibility of the code in BuildInfoCollector with Python 3. It's fixed by my PR #52. If you want, I have a build that incorporates this and a few other changes (PR #53 and #54, plus adding expansion of build variables on SCons command lines) that I can post.
