Since there were no replies to this topic so far, I have
decided to turn this into a little exercise of how to
create my own overlay of the official OE tree.

So I have created my own hierarchy and put my patch into it:

   $ cat local/packages/ipkg-utils/ipkg-utils/ipkg-py-arfile.patch
   --- ipkg-utils/arfile.py.orig	2008-09-17 12:00:57.000000000

   +++ ipkg-utils/arfile.py	2008-09-17 12:01:13.000000000 +0200

                    return FileSection(self.f, self.f.tell(), size)
    
                # Skip data and loop
   +            if size % 2:
   +                size = size + 1
                data = self.f.seek(size, 1)
    #            print hex(f.tell())
    

Then I copied the original bitbake file to my overlay and added my
patch to the file list:

   $ diff -u

Then I rebuild.  But now it fails with
