md5sum broken?

[Chuck Kuecker]

Hello,

I am developing an embedded Linux project using Ubuntu 9.10 as a 
workstation. I need to produce an md5 checksum file of a patch I need to 
modify to make the build run. The command is:

ckuecker at ckenterprises:/opt/Freescale/ltib$ md5sum 
/opt/freescale/pkgs/mtd-utils-20060302-cf-byteswap_h-1.patch > 
/opt/freescale/pkgs/mtd-utils-20060302-cf-byteswap_h-1.patch.md5

Up until last week, this worked fine. Now, I get this error when I run 
my build script:

Processing: mtd-utils
=======================
Error: corrupt md5 file: 
/opt/freescale/pkgs/mtd-utils-20060302-cf-byteswap_h-1.patch.md5, 
renamed to 
/opt/freescale/pkgs/mtd-utils-20060302-cf-byteswap_h-1.patch.md5.bad

Ubuntu did an update since the last time I ran md5sum successfully. 
md5sum --v shows 7.4, and is dated in 2009.

Anyone seen anything similar? I am wondering if the build script is 
accessing a different version of md5sum, and the Ubuntu version got 
updated. The build script has its' own paths, which I need to trace out.
