Hmmm. It is a running server that actually uses that package.

I wonder if it is the same problem we saw before on the substitute
servers (hits missing). How did we resolve those? What was the real
problem? A rebuild merely reinstates the profile on this machine. It
actually appears to be fine.

Even so the nar server gives an error for this package. Only for this
package - all others are served.

I guess I have to read some source code.
