MD5 discrepancy in 6.0-RELEASE/src/CHECKSUM.MD5

[James Long]

When I go to ftp.freebsd.org and download

/pub/FreeBSD/releases/i386/6.0-RELEASE/src/CHECKSUM.MD5

and run md5 against it, I get the checksum

MD5 (CHECKSUM.MD5) = d0dc2749908246ee8e91de602bb422b2

Inside the CHECKSUM.MD5 file, however, it says that its own
checksum should be

MD5 (CHECKSUM.MD5) = 6ee62cd847afff4cadf6648389c67a11

I can reproduce this problem on two separate hosts.  Is the
CHECKSUM.MD5 file in the /src directory of the 6.0-RELEASE media
faulty?

FWIW, the md5 sums of the other files in that directory do
match what CHECKSUM.MD5 says they should be, but if CHECKSUM.MD5
fails its own checksum, can I trust it?
