Thanks for figuring this out.

I've had some surprises with Apple's tar before, which were partially 
addressed in 8f6046b7f850.  Since I don't see reasons to support a native 
"Apple look-and-feel" for Unix tools, I've now standardized to GNU tar in 
5ff12177a067 -- once and for all within the Isabelle process environment.

The updated tar.gz bundles are again on 

Note that the Isabelle release is produced on Mac OS X for two reasons:

   * Tobias and Gerwin use special latex fonts that only work smoothly on

   * Apple demands Mac OS X to make a .dmg (via hdiutil).

Otherwise I would do the Admin/Release/build on some Linux box, since that 
reduces the potential for surprise.
