[Risolto] Errore updmap in TeX Live 2011

Scusate ma non riesco ad eliminare questo errore, fastidioso quanto innocuo, che registro tutte le volte che tlmgr aggiorna il sistema (TeX Live 2011 su Windows XP). Ecco parte dei messaggi di output:

Did you run mktexlsr?

You can delete non-existent map entries using the option
