[Mediawiki-l] Installation error on 1.5.0

[Doug Carter]

Hi all,

This *must* be a FAQ, but I've looked everywhere and can't find
an answer.

I've followed the excellent (and simple) install instructions, but when
I start the config process by going to: http://mymachine/wiki/ I get:

Fatal error: Failed opening required 'includes/SiteConfiguration.php' (include_path='/usr/sausalito/ui/libPhp:/usr/sausalito/ui/web') in /var/www/html/wiki/includes/DefaultSettings.php on line 27

Any ideas on how to correct this?

TIA,

Doug
