Is Creative Commons Attribution 3.0 compatible with GPL v2+? [closed]

Question

I have found some code that is licensed under Creative Commons Attribution 3.0 (CC-BY 3.0).

I want to pick it and put it into a program that I downloaded that is licensed under GPL v2+.

Then I want to publicly distribute the remixed work in one software-package under GPL v2+ (GPL v2 or at the users wish a later version) again.

I'm Wondering if it is possible or not. I was already looking for license-compatiblity on the GNU website, but it has only some information about the CC-BY 2.0 License:

Creative Commons Attribution 2.0 license (a.k.a. CC-BY)

This is a non-copyleft free license that is good for art and entertainment works, and educational works. Please don't use it for software or documentation, since it is incompatible with the GNU GPL and with the GNU FDL.

In that statement it's written that CC-BY 2.0 is incompatible with GPL-

So is the Creative Commons Attribution 3.0 license incompatible with the GNU GPL v2 or later as well?

More Details

Update: It has been asked to add some more specific details to this question, here they are:

1. The example bit of code that is under CC-BY 3.0 is here: example-so-5462305.php.

2. The code I'd like to integrate this into is here: Joomla_1.6.1-Stable-Full_Package.zip

My questions about license compatibility is about to incorporate [1.] into [2.] (become part of existing code in form of a PHP class member), create a patch, add it to the publicly known repository of the project that is driving [2.] and expect it to get released then with a future version of [2.].

Answer 1

It is impossible to answer unless you give some details about the bits of code you consider and how they will be combined and depend on each other. Can you provide specifics about each piece of code? Urls, etc?

For instance the famfamafam silk icons (not really software per se) are under a CC-BY license (CC BY 2.5). They are often combined with GPL-licensed code and nobody seems to care too much.
