ADDITIONAL OS VERSION INFORMATION :
Gentoo LInux 2.6.8-gentoo-r3 i686 AMD Athlon(tm) Processor AuthenticAMD GNU/Linux

EXTRA RELEVANT SYSTEM CONFIGURATION :
Using the following version of 'tail':

tail (coreutils) 5.2.1

A DESCRIPTION OF THE PROBLEM :
I encountered this problem previously but had an older gentoo system handy. On the newly installed system (2004.2 / net install) the bin would refuse to extract, spitting out 2 'tail' errors and claiming the checksum was incorrect. After several failed attempts of downloading and trying to extract I copied it to the older system (exact same file) and it worked perfectly. Since I no longer have that machine I was forced to sit here and find a solution this time around.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Gentoo 2004.2 with tail (coreutils) 5.2.1

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Edit the following in the bin file:
(note: I will use the phrase "about line" because of echo statements I had to enter in order to see if it was doing what it was supposed to be and may have changed the line numbers plus or minus 1 or 2)

about line 333:
change-> tail 1 to -> tail -n 1

about line 341:
change-> tail +486 to -> tail -n +486

about line 358:
sum1 is incorrect
change so that it read the following:
$sum1 != 13775 || expr $sum2 != 35512
