I just compiled the pkg's for testing and now stable's are compiling, so at least here they work. The readline problem can be solved by editing debian/control, just grep for it, there's only one line with readline.
For the Qt-Errors, there has been a problem some time ago, where the libs has been split, but before I got time to investigate this, it disappeared. Stable has versions before the prob, testing has one after it. It seems Ubuntu has released right in that period. But the error should tell you everything needed.
I'm thinking about building at least wx and 2.3.1 for Ubuntu too. Maybe more when I find time.
