      4. You may distribute machine-executable forms of the Software or
      machine-executable forms of modified versions of the Software,
      provided that you meet these restrictions:

      [...]

      c. You must ensure that all modifications included in the
      machine-executable forms are available under the terms of this
      license.

This has nothing to do with private usage.  It states that if you
distribute modified executables, you must make the source available 
under QPL terms.

      6. You may develop application programs, reusable components and
      other software items that link with the original or modified
      versions of the Software. These items, _when distributed_, are 
      subject to the following requirements:

      [...]

      c. If the items are not available to the general public, and the
      initial developer of the Software requests a copy of the items, 
      then you must supply one. 

This doesn't, either.  (Emphasis added.)

If so, neither of the licence provisions you point to reflects that
concern.
