I have just tested the build process, it is very simple now. There is no need to mess up with the build of the wxwidget.
The build environment is ubuntu 10.10 using qtcreator with all required packages installed from the repository. Just double click the bitcoin-qt.pro file to start the program and then click the build button.
The new client is much beautiful and user friendly. Thanks for the hard work. BTW, is it possible now in the client to send coins to multiple address simultaneously now? I see there is a button to add multiple out address.
