I have now successfully installed eric3 following Andreas' guidance.

However I did have a couple of problems to do with qmake and qconfig when installing PyQt (3 and 4). Specifically these were

a) The need to tweak configure.py to look at QTDIR first because of a shell script of qmake in /usr/bin causing the incorrect path to be deduced.
The fix was to comment out a few lines near start (around line 49):

	#for d in path.split(os.pathsep):
	#    if os.access(os.path.join(d, "qmake"), os.X_OK):
	#        qt_dir = os.path.dirname(d)
	#        break
	#else:
Im not sure if this is a Mandriva rpm issue but it comes from qt3-devel rpm.

b) The need to explicitly use the -g option because /usr/include/qt3/qconfig.h contains
	#define _MULTIARCH_HEADER qconfig.h
	#include <multiarch-dispatch.h>
which causes the parsing of the qt version to fail.


Some notes I made at the time (in case anybody else finds it useful) were as follows:

Notes for installation of PyQt4 aware version of eric3 on Mandriva

This is based on the eric3 README instructions.

	libqt4-devel-4.1.0-3mdk
	qt4-accessibility-plugins-4.1.0-3mdk
	qt4-assistant-4.1.0-3mdk

	qt4-examples-4.1.0-3mdk
	qt4-linguist-4.1.0-3mdk
	qt4-tutorial-4.1.0-3mdk

2. Build and install QScintilla
	export QTDIR=/usr/lib/qt3
	from qt subdir execute qmake qscintilla.pro
	Edit Makefile CXXFLAGS to include -fno-exceptions
	make
	make install

3. Build and install sip
	python configure.py
	make
	make install

4a. Build and install PyQt3 (watch for a message telling, that it is including
    the qtext module)
	Need to tweak configure.py to look at QTDIR first because of qmake in /usr/bin
	Commented out lines near start (around line 49):

	#for d in path.split(os.pathsep):
	#    if os.access(os.path.join(d, "qmake"), os.X_OK):
	#        qt_dir = os.path.dirname(d)
	#        break
	#else:
	python configure.py -g/usr/lib/qt3/include/multiarch-i386-linux -c -j 4 
	make
	make install

	-g option required because /usr/include/qt3/qconfig.h contains
	#define _MULTIARCH_HEADER qconfig.h
	#include <multiarch-dispatch.h>
	which causes the parsing of the qt version to fail.

4b. Build and install PyQt4
	as for pyqt3 but dont need QTDIR set to qt3 any more.

	python install.py
