Indeed, this is where any development issue such as 'how to make Samba
compile on a system that has depricated python2' should be discussed.

My best guess is that this is caused by pidl regenerating some of it's
files after the rules where changed by your sed script. 

First try again with the current GIT tree, and then let's see if we can
some up with a sensible way to handle this.  What is the right way to
find python 2.6 on all systems?  What is done for other packages - Samba
must not be the only software not yet to move to python3?
