With both Qt2 and Qt3 installed, is there an easy

Or
should I make a script to symlink the appropriate files? Or is
there
another method?
Any hints would be appreciated.

You can extend sys.path dependent on the QTDIR environment variable.
The attached sitecustomize.py gives the ideas.

# e.g. if QTDIR points to /opt/qt-3.0.1 you should
# install (or move) PyQt into
#prefix/lib/python2.2/site-packages/qt-3.0.1
# or prefix\lib\site-packages\qt-3.0.1
# on windows
# and if QTDIR points to /opt/qt-2.3.1 you should
# install (or move) PyQt into
#prefix/lib/python2.2/site-packages/qt-2.3.1
# or prefix\lib\site-packages\qt-2.3.1
# on windows
#
# If QTDIR is not set, or is empty, or the resulting
# directory does not exist, nothing happens.
