PyQt install problem

[Bruce Wolk]

Excellent advice.  I changed the QTDIR environment variable to point to
/usr/lib/qt-2.3.0 and now I have a working version of PyQt.  I still get the
warning

    Xlib:  extension "RENDER" missing on display ":0.0".

but the examples seem to run.  I can live with that.  Thanks so much for your
help.  By the way, I am really looking forward to your book.  Python and Qt make a
phenomenal combination and hopefully your book will help spread the word.

Cheers, Bruce
