Converting Max5 to Max4 with supercollider

Hello EVeryone,

For anyone who has used super collider to convert a Max5 patch to a Max4 patch via:

http://www.fredrikolofsson.com/pages/code-sc.html

I am trying to use the sample code given using supercollider in order to convert a Max 5 patch into a Max 4 patch, however I'm getting an error message. I'm not quite sure what I am doing wrong. However, when I tried to drop the folder I downloaded from your site into the ~/Library/Application Support/SuperCollider/Extensions/ folder, I got as far as the SuperCollider folder and I saw no Extensions folder. I eventually created one and dropped the "MaxPat080712" folder in there.

I didn't change any of the code for the first patch conversion example:

//simple example - convert and save on the desktop
a= MaxPat.read("/Applications/Max5/examples/max-tricks/buttonflower.maxpat");
a.saveAsMax4("~/Desktop/buttonflower.pat");

But after I hit fn & enter I got the error message below. Please help Any assistance you can give towards correcting this problem would be GREATLY appreciated.
