Install fails with "Invalid step"

[madmaze]

after extracting the 0.8rc bundle and configuring my LAMP-ish stack(debian squeeze, lighttpd, mysql, php5) when I go to "​http://localhost/installer/"

I get "invalid step"

this can be solved by copying:
cp config/db.inc.php.dist config/db.inc.php
cp config/main.inc.php.dist config/main.inc.php

and then adding in the DB credentials and by enabling the installer in main.inc.php

Should the installer do this by itself?
if not this should probably be mentioned in INSTALL, besides under "MANUAL CONFIGURATION"

It was fixed in git after the release.
