Yes, it is a problem, at least it is advertised as such on mkl release 
notes (static vs dll). I could use PATH and get away with it, but I am 
reluctant to do that, because it is really fragile. If I could be sure 
that nobody would complain about it when it does not work, then I would 
do it in a minute (codewise, it is trivial; actually, the development 
version of numscons does it, because it is useful for debugging).

But by experience with all my other packages, windows installation is 
always  what get me the most emails, because windows is more fragile, 
and its users less aware of technical issues. I am okay spending time on 
code, much less spending time on a platform which I do not use, on a 
project which I am working for free. So it really boils down to either 
someone pays me to do it, or someone tells me how to do it reliably (I 
would of course do something which works reliably, if anyone can explain 
to me how to).

cheers,

David
