To follow up:

As suggested in the manual 
<http://docs.julialang.org/en/latest/manual/packages/?highlight=internet#offline-installation-of-packages>,
 
I copied the package root directory from another (virtual) machine 
specially set up with the same operating system and identical file system 
organization.  This seems to work fine.
