Systemtap fails on IA64

[Keshavamurthy Anil S <anil dot s dot keshavamurthy at intel dot com>]

Hi,
	On IA64 (RHEL4 U2 system with stock kernel version 2.6.13 + few bug fixes), 
I installed elfutils version 0.115-0.2 directly from sources and 
systemtap snapshot version systemtap-20050903.tar.bz2, though I did not 
had any problems compiling and installing elfutils/systemtap itself, 
I am seeing problems when trying to run stap.
1) I see some stap unaligned access
2) and some errors and some undefined architecture

Here is the output, can any one let me know how can this be resolved.

---------------------------------
[root@csdor-tiger1 src]# cat test3.stp
probe kernel.function("do_fork")
{
        print("enter");
}
