No, the default for PySide Assistant should be to install into /usr.
What did you change from the defaults?

For most of my projects, I'm not using PySide Assistant directly, but
do the packaging via debhelper and friends. I do understand that PSA
is easier for people to use. My installation schema is usually the
following:

/opt/<packagename>/bin/<packagename> - the main program
/opt/<packagename>/lib/ - python library modules go here (add this to sys.path)
/opt/<packagename>/qml/ - QML files and related stuff (e.g. images for the UI)
/opt/<packagename>/... - other files that the program needs (resources, etc..)
/opt/<packagename>/<packagename>.png - the icon
/usr/share/applications/<packagename>.desktop - the desktop file

You can get all accepted options for the "install" comamnd via "python
setup.py --help install". It should be --prefix (python setup.py
--prefix=/opt/mypackage/ install).

Which version of PySide Assistant are you using? I've tried it with
the current Git master branch HEAD
(https://github.com/PySide/PySideAssistant) and a "psa init" did add
the .png file there.

Yes, although you only need it if you use some APIs. A list of which
APIs need which tokens can be found here:

I've created a mini-package about a week ago that has permissions for
the calendar (because I wanted to play with the Qt Mobility Organizer
APIs interactively to see how I can get the data). The binary package
is here:

http://thp.io/2012/maemo/python-organizer-console_1.0.0_all.deb

You can get the source package with the "dget" utility from here:

http://thp.io/2012/maemo/python-organizer-console_1.0.0.dsc

It shows, among other things:

 - how to use only debhelper and no PSA
 - how to create a script that gives an interactive console
 - how an .aegis file could look like (in debian/)

If the PSA patches that make it install into /opt are not merged soon,
and there is demand for an easier solution, I might just publish a
short guide that shows how to use debhelper 7 and some
makefile/setup.py magic to create packaging for a simple Harmattan
Python app from scratch (but I would love for someone to get PSA into
a "Store ready" state, because that's what PSA is all about IMHO ;).

HTH :)
