[okl4-developer] Error building OKL 1.5.2 for imx31 on Fedora7 & python2.5

[David Mirabito]

Hi Mike,

When you changed the python version to 2.5, are you running 2.5.0 by  
any chance? There is a known bug in python causing the 'unpack' error  
you are seeing.
Upgrading to 2.5.1(or down to 2.4) should fix this, and allow you to  
obtain a final image.

Please let me know how it goes,
  - David
