Could you perhaps be more explicit, please?  The problem with "Compiling
no file at ..." is one I can't even reproduce at the moment.

The patch you recently posted for package.el is something to do with
package.el being compiled or not being compiled.  What connection does
this have with the irritating appearance of the message in *Compile-Log*?
