Easiest is to rely on QTDIR (PyQwt is doing this now).
If you don't trust environment variables (neither do I) you can do:

QTDIR=/usr/lib/qt3 python setup.py build

or

QTDIR=/usr/lib/qt3 python setup.py bdist_rpm


The other possibility, is that you let the user edit the setup.py file
to fill in the Qt root directory.


It is certainly possible within distutils to search for the "good" Qt
directory, but that requires good understanding of distutils. I might
do something like that in the next version of PyQwt.
