  This truly is a problem that I've seen on several random machines. I 
can't seem to make head or tails with it but I know others have 
encountered it too. I've also seen things work just fine and then one 
day fail, only to have to copy the DLLs into the 
Python26\Lib\site-packages\PyQt4 directory. In all cases it seems that 
the PATH is set correctly. When I find some time I'd like to track it 
down what the issue is.
