The last PR update occured the end of June, and the cutoff date for pages getting a PR benefit was about June 5, so something that happened six weeks will definitely not be showing benefits yet on the toolbar (though its actual benefit should be felt by now).
And the issue here is pagerank, which has no voodoo involved. A link from a PR7 page will have the exact same effect, in terms of PR, to a three year old PR5 page as it will to a brand new PR0 page. There is no difference at all. (Again, strictly from a pagerank perspective.)
