Sorry, I didn't describe clearly. elfspe wasn't provided as a src.rpm, so I 
can't build it from source, but it's part of libspe2, it's under a directory 
of libspe2, which is fixed already.

I'm using ppc64 userland, ppu toolchain is from the distro (gentoo 2007.0, gcc 
is 4.1.2 for ppc64). and I've built all spu stuff as ppc64.

yup, ydl is shipping 32bit libspe and 32bit elfspe, I've compiled libspe and 
libspe2 as 64bit, so I can't use elfspe from the distro, I didn't realize 
elfspe is from libspe2, so I have the problem until I found it under libspe2 
source tree, stupid me :(

The problem now is resolved by (replace the broken /usr/bin/elfspe):

cd /usr/src/rpm/BUILD/libspe2-2.1.0/elfspe
make
cp -pv elfspe /usr/bin/elfspe
/etc/init.d/elfspe restart

Any way, thanks very much!
