[PyQt] pyuic4 problem

I downloaded a new version of PyQt and SIP and reinstalled. PyQt4
appeared to be installed properly, as was pyuic4. However when I ran
the following command:

david$ pyuic4 -d window.ui > window.py

I go this error message:

Traceback (most recent call last):

ExpatError: mismatched tag: line 63, column 4

I don't understand what this means. Should I just delete all my python
files from the frameworks folder, and reinstall everything (a new
python install, etc)?

> Just to make sure - rebuild *both* sip and pyqt, with clean source would help.  And Qt Cocoa is a must (not the Carbon version) for 64bit.  If your using Carbon, don't add --arch=x86_64 for SIP, and use the --use-arch=i386 option for PyQt.

> P.S.  I also noticed your "qgis_scratch".  Are your developing a plugin for Qgis?  I make the "official" Qgis binaries which include a bundled Qt/PyQt, and if there is something that I could do with the distribution to help, let me know (like adding the sip/pyqt executables and includes).  I didn't think about that possibility. Though I do purposely strip out the Qt includes to save space.
