Now that you provide an installer for Atlas, it may become the same problem
as MKL, can't it ?
As for the problem: if you use PATH for dll, you need:

Yes, they will complain to you for sure, but I can't see where dynamic
libraries can become a problem :
- are they numpy dlls ? is so there is a problem, I agree with you
- are they external dlls ? If so, the installer must have set up everything
so that everything works, but this is where people bark at the wrong people
: the users of the dll and not the installers.
You seem to indicate that the problem is the last dlls, am I correct ?
