7.2.3 and MD5 checksum

I just downloaded 7.2.3 (from three mirrors)
I use 'md5sum -b postgresql-7.2.3.tar.gz' to verify the md5 checksum.
According to the (all 3) mirrors the sum should be
'cf665c93a08a60e4a99db3a6dfe7ba10'.
I got '410fa7134291e8f7f45f51851a867dbd'.

My system is Red Hat 7.1 on a i386 box.
md5sum --version returns:

md5sum (GNU textutils) 2.0.11
