Can't open Addons_contrib_bundle_2.65

Hello,
I am on Mac 10.6. When I try to extract the Addons_contrib_bundle_2.65, from:
http://wiki.blender.org/index.php/File:Addons_contrib_bundle_2.65
I get a file named:
Addons_contrib_bundle_2.65.cpgz

If I try to open that, it creates Addons_contrib_bundle_2.65.zip.

opening that creates Addons_contrib_bundle_2.65.cpgz
opening that creates Addons_contrib_bundle_2.65.zip

and I haven’t gone more that 10 itterations, but I don’t think there is 20 nested zip files.
Is there any way to actually extract the contents on a mac?

Thanks for any help,
-Dylan

nm, I figured out it’s a problem with the mac archiver utility.
then, I gave up and opened with 7zip on a windows machine.
