Hi all, after install nginx using EPEL (yum install nginx) in CentOS 5.5. I tried to start the server, but I got this error:

2011/01/18 15:56:58 [emerg] 2139#0: eventfd() failed (38: Function not implemented)
2011/01/18 15:56:58 [alert] 2138#0: worker process 2139 exited with fatal code 2 and can not be respawn

2011/01/18 16:01:15 [alert] 2260#0: worker process 2261 exited with fatal code 2 and can not be respawn

I need to compile the nginx instead using yum?
Thanks a lot.
