When you downloaded the SDK, did it come along with QT libraries?
(check 'lib' folder under the install dir)

I downloaded the linux version (I'm running Ubuntu 10.04) from here
(did not use apt):
http://qt.nokia.com/downloads/sdk-linux-x11-32bit-cpp

The lib folder under the SDK install folder has all the required QT libraries.

If at runtime it's not able to find the libraries, did you check if
the QT lib folder is there in your env's LD_LIBRARY_PATH var?

HTH,
