It seems that artwork-common has only a subset of the artwork.
Now one needs *both* artwork-common and the artwork zip file.

This is why I thought the artwork was required.  It is on windows.

I already have some changes along these lines underway.  Currently it
can be an option only on Linux and Mac.  Windows requires art to build.
