Numpy is working with your Python2.6 and 2.7 installations, but as  
Pauli pointed out,
the script you want to run instead is using instead a different and  
very ancient Python library,
Numeric (which in its days occasionally was referred to as "NumPy",  
too, just to add
confusion ;-).
This means you could either try to

- get Python2.4 to work on your machine and hope the Numeric binary  
works with it

- compile Numeric from source for your Python2.6 or Python2.7  
installation (it actually
   still builds with Python2.7), but this might be challenging for a  

- try to modify your script to work with numpy instead. Numpy provides  
all the functionality
   Numeric has ever offered afaik; its syntax is merely slightly  
different in a few cases.
   You should find some helpful information here:


   (please note the caveats about the automatic converter!)
   It might even be enough to replace the line in the script
   File "AbinitBandStructureMaker.py", line 16, in <module>
     from Numeric import *
     from numpy.oldnumeric import *

   ymmv - if you can contact the maintainer/original author of the  
script, you might ask
   them for assistance - it does not make much sense to rely on a  
software package that
   has not been maintained for half a decade, after all.
