what causes error -- ELF interpreter /libexec/ld-elf.so.1 not found

[Jin Guojun [VFFS]]

I have multiple FreeBSD 6.2 machines with different hardware, but one of 
them encountered
this strange error when running program "wine".
I could not figure out what causes such error since /libexec/ld-elf.so.1 
absolutely exists, otherwise
no program will run.

It does not matter if the wine is pre-compiled in packages or I built it 
from ports.
All other machine do NOT have such problem.

I reinstalled this machine a few times, and it always does the same 
thing. However other programs
run well.
Would this is related to some particular hardware issue?
This one is ECS 848P-A7 motherboard with Intel P4 506+ CPU, plus 2 GB 
memory.
Other machines are HP AMD64 laptop, DELL Dual XEON, DELL Intel Laptop, 
and AMD XP 2100+,
and none of them ever had such problem.

Does someone have an idea what is happening here?
