You need to compile and install the qscintilla C++ lib before generating the 
python wrappers:

pushd Qt4
qmake qscintilla.pro
sudo make install
popd

Al, manually compiling stuff like this should be done as the last resort 
only.

One of the most compelling reasons to use Linux is the distributions package 
manager. OTOH, mixing that with manual builds is the source for many 
strange failures. 

My advice is: go through the hassle of building packages for your 
distribution. Even better, as far as I know, Ubuntu has something similar 
to openSUSE build service, or you might want to use that, since it is able 
to create ubuntu builds, too.  

Just needing the packages on a second system will pay off for the initial 
hassle. Guaranteed.
