this is due to the preference given by Windows to load dll's from the
same directory where the program is resident instead of using the
ones in the PATH

I have the same issue when testing a new version of
GraphicsMagick perl interface

The perl program located in /usr/bin will alway use the installed
GM dll's  in the same directory instead of the new one I am trying
to test.
