libevent checksum error

[myron]

I was trying to install ntop when I got a error on installing the  
dependency libevent. This is what
the log file says:

version:1

:info:checksum The correct checksum line may be:

:notice:checksum Log for libevent is at: /opt/local/var/macports/logs/

What's the best way to correct this?
