After getting fed up with using someone else’s out of date versions, I decided to compile my own Qt, SIP, and PyQt for x64. I managed to get it all working and figured I could share it up, so here’s a link to the installers, as well as the latest version of sip.pyd which you will need.
Both are the latest PyQt4 4.7.3-1, however they are compiled against different versions of QT.
PyQt-Py2.6-gpl-4.7.3-1_QT_MAYA.exe is compiled against Qt 4.5.3 (2009.04) which Maya 2011 uses, the other is compiled against the latest Qt 4.6.2 (2010.02.1).
Also, please note that I did not include any components that do not come standard with the Qt SDK such as QScintilla.
Edit: A few people were unable to get this working, not sure why but here’s an alternate version without the installer that seems to fix any issues with Qt failing to import
