You'll probably need to replace the hardcoded paths to a dynamic path, replacing with modplug.dll for windows, and libmodplug.so for Linux.  What's not finished yet is the code to call the proper function to play the song.  I'm hoping someone smarter than me might be able to figure that out!

You can get Modplug.dll by downloading [url=http://alister.eu/jazz/oj/download.php]OpenJazz[/url] (an open source Jazz Jackrabbit clone).  From there, this source file can presumably be called to load the functions.  Whew....
