Dear Lawrence,

my version information.

* Structure !VERSION, 7 tags, length=44:
   ARCH            STRING    'x86'
   OS              STRING    'linux'
   OS_FAMILY       STRING    'unix'
   RELEASE         STRING    '5.4.1'
   BUILD_DATE      STRING    'Jan 16 2001'
   MEMORY_BITS     INT             32
                   INT       =       32

As Craig too I don't have this failure you got.
