 *   Hmm .... this ports use the same distfile as x11/aterm, and I fetched  from
 *   the two MASTER_SITE, use md5 to check it - seems ok.
 * ===Like this============
 *   Receiving aterm-0.3.4.tar.gz (290321 bytes): 100%
 * 290321 bytes transfered in 0.3 seconds  (918.04 Kbytes/s)
 * ===>  Extracting for zh-aterm-0.3.4
 * >> Checksum OK for aterm-0.3.4.tar.gz.
 * ========================
 * 
 *   This file is 290321 bytes, I'll put it under my freefall's account and
 *   add a MASTER_SITE http://www.freebsd.org/~foxfair/ to the end.
 *   Hope the error message won't confuse anybody anymore. 

That doesn't solve anything.  I already fixed it according to
cpiazza's suggestion, but let me try to explain.

See, the problem is this:

(1) master-site-a has file with checksum A and master-site-b has file
    with checksum B.  Both are valid tarfiles and will extract exactly
    the same.

(2) You only have checksum A in files/md5.

(3) The port works only if master-site-a is feeling fine.  If it's
    down, the file will be fetched from master-site-b and the checksum
    will fail.

Adding another site with checksum A after master-site-b won't prevent
the problem from occuring.

Do you understand?
