I did a patch to compile as a user but nobody liked it (this 
applies to sip and PyQt as well). The basic reason is that 
python/site-packages isn't world-writable, if I recall 
correctly.

Can you run importTest.py (in the top level PyKDE directory) ? I 
expect it will fail the same way.

The only occurance of 'getFormat' (with 'sipName_' prepended or 
not) I could find on my system was in PyQt/sip/qtextedit.sip:

	// These are undocumented and marked as "don't use".
	//virtual bool getFormat(int,int,QFont *,QColor *,
                                            VerticalAlignment *);
	//virtual bool getParagraphFormat(int,QFont *,QColor *,
	//				VerticalAlignment *,int *,
	//				QStyleSheetItem::DisplayMode *,
	//				QStyleSheetItem::ListStyle *,
	//				int *);

The problem you're seeing is that none of the libs are providing 
'sipName_getFormat'. The 'sipName_' part means that sip has seen 
the symbol getFormat somewhere, and seems like it had to be in 
PyQt. The first thing I would check is qtextedit.sip and see if 
yours corresponds to the above. I can't find anything in KDE, 
PyQt or PyKDE referencing getFormat on my system, so I expect it 
has to be a Debian difference, or .....

Make sure you have sip 3.6 or 3.7 (sip -V) and PyQt 3.6 or 3.7 - 
sip versions (what the 3.6 or 3.7 means everywhere) have to be 
the same for everything. PyQt 3.5 had getFormat enabled. PyQt 
3.5 and/or sip 3.5 won't work with this version of PyKDE.

You can check your PyQt version in the Python interpreter:

>>> from qt import PYQT_VERSION_STR
>>>PyQT_VERSION_STR
'3.7'

If PYQT_VERSION_STR isn't available, your PyQt is too old. 
build.py for PyKDE checks this, but only when trying to figure 
out where PyQt's sip files are located, and you're specifying 
that with a switch so the check isn't done.  build.py should 
check all that version stuff, as it's a constant source of 
problems - added to 'todo' list.

I think Ricardo has 3.6 or 3.7 versions of sip and PyQt packaged 
for Debian.
