I looked in the source, and it appears the print statement is printing
the value of the 'parameters' key stored in the Info hash without
checking to see if it exists. When you use the module with a compiled
file, no value is stored for that hash key. If I've interpreted the code
correctly, adding
parameters => "",
to the Info hash should keep it quiet. In that case, reporting a bug
would be a good idea.
