selfupdate always updates macports bases even if the installed version is the latest

[Giuseppe Miceli]

	ciao,

on a specific machine, everytime i selfupdate macports, it detects correctly the installed macports base versions installed and available and even if they are the same version it updated macports base (see iterm dump below pasted).

don’t know if it’s my fault or some stale file around or else? am i supposed to open a ticket on trac or is it a trivial thing? 

thank you very much in advance,
