Right now, it simply appends an extension like ".dll" or ".dylib". It<br>
doesn't handle versions or anything like that.<br>

<br>
Yeah, that sucks. I'm not aware of a better general solution. In some<br>
cases, you might get away with searching for "*png*.dll" then loading<br>
that using load-foreign-library, but I suppose you need to be careful<br>
where you search.<br>
