How does one get from "ImportError: DLL load failed:..." to a culprit .dll and symbol?

LOL, I am that person :p
Your technique works well and it does provide the information and it is 
a (roundabout) solution to this class of problems:  thank you very much. 
It doesn't answer the original question so I'll restate it:

How do you get *Python* to tell you the dll and the problem symbol? Not 
external tools, Python. Python at a low level is calling LoadLibrary and 
GetProcAddress to resolve symbols and the call fails. At that point it 
has the name of the dll and the problem symbol to hand and yet strangely 
only gives an opaque error message. How does one get Python to print out 
the faulty DLL and symbol?

(Even if it means a debug build of Python and adding the printf 
yourself, I just want to know where we stand on this issue! :) )

Best Regards,
Chris
