How are you launching your program? Are you using pythonw instead of
Python? That's how to launch Python GUI programs on Mac OS X.

Do you have the MacPython add-ons installed? These make double-clicking
on Python apps the easiest way to launch them. See

Also, my installer package is now live. See It installs most stuff
directly, then you just need to run sudo make install in the directories
for PyQt and Sip. It's a straightforward build, nothing fancy, and works
fine for me. Perhaps you should give that a try and see if you find it

When I try to assemble a standalone verison of a PyQt app (using py2app,
like py2exe but on the Mac, with the Qt libraries), I do have problems
seeing the PyQt path--I get some of the same error messages that you are
seeing. I haven't figured out how to debug those yet. However, when just
running the script, or doing an applet bundle
(, things
run fine. I've bundled up Eric3 (released with my PyQt distro) and Kodos
(just on my own box) this way, and they work fine.
