I used to use kazehakase regularly, because they kept promising gtk+ webcore support. IIRC back then it entirely depended on having a full mozilla/seamonkey/firefox install present just to build at all, even if you compiled it with a different rendering engine. Then ,after the build was done, you *still* had to keep another browser installed just to use this one. Seems like they've overcorrected for that :)
