I am hacking on the PySide installer for use in PIP or easy_install.

Actually, this work is temporary, since I'm aiming at some review
and inclusion into pyside-install.

The original version is from Roman Lacko.
https://github.com/PySide/pyside-setup

Then, Daniel Brett wrote OS X support and sent a pull request.
This was the real work, I want to give all credits to Daniel and Roman.

I grabbed that pull request, turned it into a bitbucket project
and extended it with a few work-arounds, and finally used
macholib to create the "--standalone" modus.

You can find the relevant addition here:

https://bitbucket.org/pydica/pyside-setup/changeset/4b8be97e5a00b577fe30ce9aa7e5723ff2a66f94

Note that this repo is on bitbucket since I'm used to it.
You can see the complete history here:

This is not mean to be a fork, but just a clone, with the intent to
prepare for inclusion.

The use-case was laziness:
Instead of adding a complex analysis of the references, I simply used
macholib and let it do its thing, because the wheel was already invented.
I'd also like to move more stuff to macholib instead of using the mac tools.

The references to frameworks work great.
The only wart is the rewrite of the names of plugin modules,
which simply should not happen.

But it is not a big deal, since I have to add a qt.conf file, anyway.
(the last missing thing in my setup).

Cheers - Chris
