Lighttpd: plugin-version doesn't match lighttpd-version for fastcgi

[ATC]

Server was running a home-baked version of lighttpd because of reasons that no longer apply.

After updating lighttpd using yum, it refuses to start:

$ service lighttpd start
Starting lighttpd: 2009-02-09 18:13:55: (plugin.c.417) plugin-version doesn't match lighttpd-version for fastcgi
2009-02-09 18:13:55: (server.c.859) Initialization of plugins failed. Going down.

For some peculiar reason, the fastcgi module is installed (and therefore updated) as a separate module.

$ yum install lighttpd-fastcgi

This will replace your home-baked fastcgi module and lighttpd is happy once more :-)
