PyInstaller and PySide and QtGui - pyside

Question

I'm having a similar problem to the post:
Pyinstaller: ImportError: cannot import name QtGui
... however this post does not appear to have a solution. I cannot use pyinstaller to install the very simply PySide script (helloWorld.py):
#!/usr/bin/python
import sys
from PySide import QtGui
from PySide import QtCore
app = QtGui.QApplication(sys.argv)
label = QtGui.QLabel("Hello Plain World")
label.show()
app.exec_()
sys.exit()
I run:
]$ ./makespec.py -F helloWorld.py
]$ pyinstaller helloWorld.Spec
which generates:

This successfully produces an executable but when I run it I get the following output:
Traceback (most recent call last):
File "<string>", line 4, in <module>
ImportError: cannot import name QtGui
My system is Linux Mint 15 (ubuntu 13.04), have PySide and PySide-dev installed and used quite a bit, I am using pyinstaller 2.0.
Any help would be GREATLY appricated.

This is likely related to hidden imports that the analysis cannot detect. From the manual:
If Analysis thinks it has found all the imports, but the app fails
with an import error, the problem is a hidden import; that is, an
import that is not visible to the analysis phase. Hidden imports can
occur when the code is using import or perhaps exec or eval. You
get warnings of these (see Build-time Messages). Hidden imports can
also occur when an extension module uses the Python/C API to do an
import. When this occurs, Analysis can detect nothing. There will be
no warnings, only a crash at run-time. To find these hidden imports,
set the -v flag (Getting Python's Verbose Imports above). Once you
know what they are, you add the needed modules to the bundle using the
--hidden-import= command option, by editing the spec file, or with a hook file (see Using Hook Files below).
Try adding the following to your spec file's Analysis section:
hiddenimports=['PySide.QtCore','PySide.QtGui']
