Hi Chris
Darn!  It worked this morning and I don't know why.

Focused on PyInstaller because it creates a single executable.  Testing on 
all major versions of Windows (32-bit and 64-bit), Linux and OSX.  The 
problem OS is unsurprisingly, Windows XP (SP3).

Numpy was upgraded to the mkl-version and maybe that did the trick.  Tried 
to replicate on an identical Windows XP machine using the standard 
sourceforge distribution but that resulted in a pyinstaller error.

Anyway, using the latest releases of all software ie. Python 2.7.3, Numpy 
1.7.0, Scipy 0.11.0, PyInstaller 2.0.

Will post back if run into problems again.  Best ...
