problem during Qt installation

I'm currently downloading Qt4 and I got to about 85% of the downl开发者_如何学Pythonoad, when an unexpected error message popped up, saying...

Error during installation process(com.nokia.ndk.tools.simulator.qtgcc): Error while relocating Qt: Can't start process install_name_tool.

What should I do? I'm not sure what the problem is.

EDIT: I'm downloading this on the snow leopard operating system and I've tried the online installer and the full package download.

All you need to do is install GCC - that comes with Xcode ! I had the same issues Lion, I installed gcc, and reinstalled QT... things went smooth. to double check if you have the same issues, use " which gcc" and see if you have gcc.

To install gcc, go to Xcode->Preference->Downloads and click install button besides "Command line tools".

I reinstalled xcode (from the apple developer website) and selected all the options that come with the package this time. I had no more problems during the installation.
