Not that I have any clue about (what sounds like) Win32 dynamic linking, but the underlying Perl C APIs changed between 5.6 and 5.8. Generally it's not guaranteed that the C API will be binary compatible between different Perl versions. You'd be better off providing the libraries for the version you used that you know work with your app rather than trying to be (too) flexible and accommodating of what the user might have installed.
