Can't open Addons_contrib_bundle_2.65

I am on Mac 10.6. When I try to extract the Addons_contrib_bundle_2.65, from:
I get a file named:

If I try to open that, it creates

opening that creates Addons_contrib_bundle_2.65.cpgz
opening that creates

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,

then, I gave up and opened with 7zip on a windows machine.
