For linux - yes - I think that should be easy with a combination of
``ldd`` to find the dependencies and ``patchelf`` to set the rpath to
point to the copied library.

For Windows - I believe that it is not possible to set relative paths
for windows DLLs, but I'd be very happy to be corrected.  There is a
function SetDllDirectory [1], but this would need some extra extension
code in the package.  Windows experts - is that an option?

Cheers,

Matthew
