I'm installing iRedmail on a clean RHEL 5.4 server, first time, after set password for www@domain.com, it stoped for about a quarter, I pressed Ctrl+C to start over, and then it stopped after downloading source tarballs, shown in the screenshot attached.
I wonder what's go wrong, how to fix this?

Lots of thanks for the touching tips for Chinese users
