No, it means something may have changed in between the time the developers wrote the code and when he tried to run it. Or perhaps there's something interesting in his environment (e.g. a different file system than the installer supports). But since Greg didn't bother burdening anyone with details, we'll never know.

The link I posted is a perfect example of this - it's for the supervise utility from djb's daemontools. djb is one of sharpest programmers out there but I doubt he considered that years after he wrote daemontools someone might want to run it on a platform where poll behaves as it does.
