</div>Ah, I should have thought of using strace...<br>

</div>I'm not sure these failures are the cause of the problem. I see the same<br>
failed calls to open() in my output. However, if you look through the<br>
output, you should see that some of these files are found in other places,<br>
such as in the Python installation's site-packages directory.<br>

</div>I would be surprised if the python-sip4 package was missing - if I try to<br>
remove it, apt-get tells me that it will also remove python-qt4, so the<br>
plugins example wouldn't have run without it. I don't have any of those<br>
-dev packages installed, so it would be strange if our systems behaved<br>
differently in this respect.<br>

Could it be that your system was finding an orphaned sip.so library<br>
somewhere? Did you install Ubuntu from scratch or did you upgrade from a<br>
previous version?</blockquote><div><br><br>Turns out there is a dependency on python2.6-dev, specifically /usr/lib/<a href="http://libpython2.6.so">libpython2.6.so</a></div></div>
