Nokia realised qt sdk beta. http://www.forum.nokia.com/info/sw.nokia.com/id/e920da1a-5b18-42df-82c3-907413e525fb/Nokia_Qt_SDK.html Is it possible to run it on archlinux?
Hm, it is able to run, but unfortunately there is too new libpng version in archlinux.
Just download the binary from here: http://qt.nokia.com/downloads/downloads#lgpl
http://aur.archlinux.org/packages.php?ID=33795
Or you can just clone download the source and build it yourself which will then use the newer libraries (but that may not work correctly).
As an arch user you should know how to use AUR. This really doesn't belong on stackoverflow, this is a question for the arch forums
