When you say find/use, can you please clarify whether you have completed the compilation/linking successfully? I'm not clear on exactly when you're having problems. What is the error output?
One very helpful tool in diagnosing dll problems is dependency walker: http://www.dependencywalker.com/ It may be that your openblas has a dependency that it can't load for some reason. Dependency walker works on .pyd files as well as .dll files.
