Try running ldd /usr/autodesk/maya/lib/python2.6/site-packages/PyQt4/QtCore.so
Most likely what your PyQt is compiled with different version of gcc. Maya uses still uses 4.1. So, I don't know if maya 2011 distributes headers for Qt it uses, I guess it does. You will need to download sources from sip and PyQt from riverbank site. Upack them somethere. Also install gcc-4.1, I'm sure ubuntu has such package. make a link to gcc-4.1 and g++-4.1 to your $home/bin dir. cd ~ mkdir bin cd bin ln -s /usr/bin/g++-4.1 g++ ln -s /usr/bin/gcc-4.1 gcc gcc-4.1 executable may have different name in ubuntu. We link it to your home dir, so we do not override system default /usr/bin/gcc and g++. cd into/sip/dir mayapy configure.py make sudo make install (this will install sip into maya/lib/python2.6/site-packages cd pyqtdir mayapy configure.py -q /usr/autodesk/maya/bin/qmake (I home maya has qmake distributed) make sudo make install (will install into maya python site-packages) mayapy -c "import PyQt.QtCore" for testing. -- http://groups.google.com/group/python_inside_maya
