samba failed MD5 Checksum

Hi all:

I am trying to compile the smaba34 but somehow it failed MD5 Checksum and SHA256 Checksum:

--------------------------------------------------------
# make all
===>  Vulnerability check disabled, database not found
===>  Found saved configuration for samba34-3.4.5_1
===>  -------------------------------------------
===>  Run 'make config' to (re)configure the port
===>  -------------------------------------------
===>  Extracting for samba34-3.4.5_1
=> MD5 Checksum mismatch for samba-3.4.5.tar.gz.
=> SHA256 Checksum mismatch for samba-3.4.5.tar.gz.
===>  Refetch for 1 more times files: samba-3.4.5.tar.gz samba-3.4.5.tar.gz 
===>  Vulnerability check disabled, database not found
===>  Found saved configuration for samba34-3.4.5_1
===>  -------------------------------------------
===>  Run 'make config' to (re)configure the port
===>  -------------------------------------------
=> samba-3.4.5.tar.gz doesn't seem to exist in /usr/ports/distfiles/.
....
---------------------------------------------------------------------

actually "samba-3.4.5.tar.gz" does exist under /usr/ports/distfiles

how could I fix this problem? I am using 7.2-p7...

Thanks
