[PyQt] no SQL Drivers available (Gentoo-Linux)

Hello Phil, hello Mailinglist,
I have gentoo-linux (quite up to date) with PyQt 4.3.3 and Qt 4.3.3 and all
with Python 2.4 (that's an Gentoo issue) x86_32 platform.
Gentoo compiles QtSQL-Drivers as plugins only, so I have on the Qt side sqlite
nergal at kutha /usr/lib/qt4/plugins/sqldrivers $ ls
libqsqlite.so libqsqlite2.so libqsqlpsql.so
This is the last idea I have got:
that they need to be compiled as:
-qt-sql-sqlite instead of -plugin-sql-sqlite
but it would mean to manipulate a lot of ebuild-stuff from Gentoo to get this
to work, which I do hesitate to do, 'cos other software I need rely upon a
PyQt compiles with QtSQL:
nergal at kutha /usr/lib/python2.4/site-packages/PyQt4 $ ls
Qsci.so QtDesigner.so QtScript.so QtXml.so elementtree uic
Qt.so QtGui.so >>> QtSql.so <<< __init__.py pyqtconfig.py
QtAssistant.so QtNetwork.so QtSvg.so __init__.pyc pyqtconfig.pyc
QtCore.so QtOpenGL.so QtTest.so __init__.pyo pyqtconfig.pyo
I can access databases directly from Python or with non-python Qt
applications, so I assume there is no malfunction to be expected.
Even the example from PyQt4 does not work:
nergal at kutha ~/Python/PyQt4/examples/sql $ python
Python 2.4.4 (#1, Oct 26 2007, 16:35:26)
[GCC 4.1.2 (Gentoo 4.1.2)] on linux2

I am at the end of my rather modest wits ;) - I do not see what's going wrong.
Any hint would be great.
