dowser, welcome to hydrogenaudio!
Nice to see that you found this thread, after searching Google for a while, and that you appreciate the binaries I have compiled.
You can run them from their current location, or you can put them somewhere in your Path.
/usr/local/bin/ is usually used for 3rd. party applications.
1. Check if /usr/local/bin/ is in your path. Open Terminal and run "$PATH" (without the quotes), and see if it is listed.
2. Copy the binaries to /usr/local/bin/ , or any other directory in your path (ex. /usr/bin/ ):
Mount the Disk image before you proceed!
CODE
sudo cp /Volumes/WavPack/wavpack /usr/local/bin/
sudo cp /Volumes/WavPack/wvunpack /usr/local/bin/
sudo cp /Volumes/WavPack/wvgain /usr/local/bin/
3. Call the applications by running their name. Ex. "wavpack"
Just ask if you need more help!
