For my Ubuntu 7 machine, the DNS resolution was not working on IPv6. This is a 2007 release that I don't want to upgrade.
Check and see if a 'dig -aaaa www.site-u-want.com' resolves to a valid address. That was one of my first clue that something was wrong.
I did not do much investigation for the Mac. Quick cure (not a fix) for my needs at the time.
