thunderbird checksum error

["Mark Par" <mrbpar%gmail.com@localhost>]

Hi,

I have a problem installing thunderbird.  The checksum of the file I
get is different from the one on its distinfo.  I have tried to
download from both the official site and the NetBSD site.  Is anyone
having the same trouble?

I've experienced this once or twice and getting the distfile from
ftp.NetBSD.org would solve it.  What could be causing this?

I am using GENERIC.MP 4.0_BETA2 system with pkgsrc-2007Q1.
