Actually, no he doesn’t. Just linking back to the Wikipedia page is insufficient. To whit:

Mahalo has a link to the CC-BY license 3.0 (even though the link is oddly titled "CC License 2.0"). It is not acceptable to take content from wikipedia (licensed under CC-BY-SA 3.0) modify it, and release it under a different license with conflicting terms.
This could be cleared up by unambiguously stating on the Mahalo pages that the content was available under the CC-BY-SA license 3.0, and providing a link directly to the terms of the license.
In fact as a wikipedia user, contributor, if I remember right the change form CC2 to CC3 at wikipedia was done to handle these sort of issues with credit not being given correctly..
