new version of disp+work

Hello

I need to apply a new HR patch (SAPKE470B5) which requires SAP Note 1497003. This itself requires a new version of disp+work. We are running SAP 4.7, Oracle 10g, Solaris 10.

The note says:

Please update your kernel at least to the patchlevel indicated in the SP Patch Level section of this note. 
Please note that the kernel patch package referenced in the SP Patch Level section is the "disp+work package". 

The level indicated in the note is SP353. The version on the Service Marketplace is now 368 (which I assume shoudl still work OK). I have downloaded this to our server

SAPCAR gives the following messages:

:/usr/sap/trans > SAPCAR -xvf dw_368-20000221.sar
SAPCAR: processing archive dw_368-20000221.sar (version 2.01)
x disp+work
SAPCAR: error in GetEntryData(); unknown block type (error 100). No such file or directory

Bus Error(coredump)
:/usr/sap/trans >

I also tried the latest version fo SAPCAR (from the Service Markepplace) but this seems to be worse:

:/usr/sap/trans > SAPCAR -xvf dw_368-20000221.sar
Illegal Instruction(coredump)
:/usr/sap/trans >
:/usr/sap/trans > SAPCAR -tvsf dw_368-20000221.sar
Illegal Instruction(coredump)
:/usr/sap/trans >

I suspect I'm doing something wrong that's fairly simple. Can anyone offer any advice? (I haven't done this before so it's entirely possible that I've missed what should be an obvious step)

Thanks, Chris
