I am developing a site for a client, let's call it whatever.com. He wants to have his Tumblr blog at whatever.com/blog. (Tumblr lets you name the URL at which your Tumblr page will be served, and if it's a site root, you adjust your domain's A-Record, which obviously I can't do here.)
Right now I have a blank page called blog so that it shows up in the nav using wp_list_pages(), but I'm guessing this won't work unless I do some fiddling elsewhere.
Anyone know how to do this?

.htaccessto rewrite? But to me, that counts as hacky. Better to just use WordPress, methinks. – Isaac Lubow Aug 3 '11 at 1:07
