With a few patches I manage to build out of place (install after building)
without the RPATH magic: sip-3.9, PyQt-3.9 and a PyQwt (no install necessary
to run the examples).

The trick was to add -Wl,-soname$(TARGET) to LFLAGS.
Is there any distro that dares to touch LFLAGS_SONAME :-) 

Attached you'll find build-scripts and patches to see what I have done.
(Python-2.3.2 lives in /home/packer/usr/bin, so prefix=/home/packer/usr)
