Unsupported relocation type

[Alan David Brunelle]

I'm starting to utilize SystemTap (btw: this is _really_ cool stuff), 
anyhow, I've been able to run a script on an Opteron system (RHEL4 U3), 
but on an IA64 system (RHEL4 U3) I see the following error :

[root@powis 06_09]# stap -vg scwrite.stp
Pass 1: parsed user script and 10 library script(s) in 79usr/0sys/80real ms.
semantic error: cannot find module scsi_mod debuginfo: Unsupported 
relocation type
semantic error: no match for probe point
         while: resolving probe point 
module("*scsi_mod*").function("scsi_dispatch_cmd")
semantic error: cannot find module scsi_mod debuginfo: Unsupported 
relocation type
semantic error: no match for probe point
         while: resolving probe point 
module("*scsi_mod*").function("scsi_done")Pass 2: analyzed script: 2 
probe(s), 4 function(s), 7 global(s) in 2usr/1sys/4real ms.
Pass 2: analysis failed.

As noted, this runs fine on the Opteron box. stap -V returns:

[root@powis 06_09]# stap -V
SystemTap translator/driver (version 0.5.4 built 2006-02-02)

Googling around showed that a similar error was fixed by going to 0.5.4 
- is there something IA64-specific I should be looking at?

Thanks,
