How to build webkit and webkitgtk from source

[John McLean]

Hi all:

I want to build webkit and webkitgtk from sources under linux (ubunto). 
On webkit.org theres only directions for mac and windows. The debian 
packages I've found for webkitgtk only have headers, not all the source. 
I haven't found directions how/where to get direct from svn, and if it's 
possible, is the gtk port include in the svn trunk.

Thanks much.

John
