Can't run PyQt apps with MacPython

[Morad]

I recently got a new MacBook Pro with Leopard, and would like to
develop using Python and PyQt. I installed the latest Qt SDK, updated
MacPython to V 2.5.4 and then proceeded to install SIP and PyQt as
described in Mark Summerfield's book on PyQt Programming. Everything
went fine and none of the scripts complained. However when I want to
run a demo app, I get the error message "Fatal Python error:
Interpreter not initialized (version mismatch?) / Abort Trap". Anybody
can help?

This page suggests a possible conflict between installed Python
interpreters:

A post to the PyQt mailing list talks about the correct way to build from
source, but it may not be relevant in this case:

It may just be worth checking that SIP and PyQt were built and installed
for the interpreter you expected. Failing that, you might want to ask this
again on the PyQt mailing list:

Thanks David. What I managed to do as an interim solution is simply to
remove MacPython and reinstall SIP and PyQt using the default version
of Python that comes with Apple, and then everything works. Next I
will retry how to use a more uptodate version, maybe I compiled SIP
etc. with the wrong version. If I have more questions I will use the
PyQt mailing list, thanks for the tip!

Quick update: I now also managed to get things working with a newer
version of MacPython (2.5.4) and everything looks fine. The trick
seems to be that if a terminal window is open prior to the MacPython
install, it will NOT use the new version of python. So one has to
close it and open a new terminal window, and only then should one
compile SIP and PyQt.

Anyway, thanks again for the help.
