Comment (by bgamari):

 > In this case I suspect you've set up the buildbot on a completely new
 Windows install. In which case you're probably missing the proper
 Microsoft C Runtime. (Windows update would eventually get to this).

 Indeed you are right, this is a clean installation. Unfortunately the
 problem seems to persist after installing the VC2008 runtime (both 32- and
 64-bit for good measure). Moreover, there is no sign of any relevant
 events in Event Viewer.

 Sadly my usual `strace` approach seems powerless on Windows: I can see an
 `open` system call for `ctypes/__init__.py` but nothing else interesting.
