There are some 64-bit related issues when using PyQt and Snow Leopard. There’s the way to resolve it by reverting to 32-bits:

  1. Get the latest versions of PyQt and SIP. You need Qt installed of course.
  2. Configure SIP using
    3. python configure.py --arch i386
  3. Configure PyQt using
    4. python configure.py --use-arch=i386
  4. Finally, make sure your python is running in 32-bit mode because current Qt doesn’t support 64-bit mode. Add 
    export VERSIONER_PYTHON_PREFER_32_BIT=yes

    to your .bash_profile in your home directory

  5. If your Python still refuses to run in 32 bit mode, try 
    arch -i386 python
