Please see the updates below to get the latest Midori and Webkit for Ubuntu.
Also, you can go here for support, Stemp seems busy ;)
This is a translation of the midori article written in French by my friend Stemp. midori is a web browser using the webkit engine. If this is of some interest to you, there is also an epiphany-webkit package in Bruce Cowan’s PPA.
As far as I know, Stemp has packaged midori for Ubuntu, but some libs need to be upgraded from the debian repos.
Translation:
The biggest problems with compiling on Ubuntu are the older webkitgdk libraries.
Debian Unstable has the latest libwebkitgtk :
The libwebkitgdk-dev package from Ubuntu will need to be uninstalled.
The midori sources are here: midori-0.0.10 (currently an early alpha).
To compile:
./configure make sudo checkinstall
Install the package and go!
Please check the screenshots on Stemp’s blog page (first link).
Edit1: midori-0.0.11 is now available.
Edit2: There is now a midori package for gutsy in Stemp’s PPA. The procedure to install with your favorite package manager is here.
Edit3: Midori 0.0.12 is now available on Stemp’s PPA.
Edit4 – 071208: Midori 0.0.13 et Webkit svn 283+ now available on Stemp’s PPA. Please note that webkit svn28482 will prevent current version of epiphany-webkit from running.
Edit5 – 080512: midori-0018-and-webkit-33023 now in Stemp’ PPA.
Edit6 – Midori 0.1.1 and WebKit 38850 from the webkit-team PPA with install instructions for Ubuntu.
Edit7 – Midori 0.1.5 and WebKitGtk+ 1.1.3 for Ubuntu Hardy, Intrepid & Jaunty.

Ooh! I like trying new, lighter browsers. … :)
Will it compile on a nslu2 with native debian on it? (arm based)
