lighttpd fastcgi issues

Suddenly "mod_fastcgi" being enabled in "server.modules" for lighttpd is causing problems.

 2011-04-21 19:30:58: (log.c.166) server started
2011-04-21 19:30:58: (mod_fastcgi.c.978) bind failed for: unix:/var/run/lighttpd/php-fastcgi.socket-0 Permission denied
2011-04-21 19:30:58: (mod_fastcgi.c.1399) [ERROR]: spawning fcgi failed.
2011-04-21 19:30:58: (server.c.938) Configuration of plugins failed. Going down.

Fix:

[youri@nemesis run]$ sudo gpasswd -a youri http
Password:
Adding user youri to group http

Or I should maybe make lighttpd run as http user again.
