Until here I can't really follow. It seems that you compiled everything
from rpms except the elfspe2 library.

Did you compile the mixed spu+ppu on your own or did you use the
precompiled ones? Anyway, which arch is it (ppc32 or ppc64)

I guess the problem is your 64bit userland. Do a 
 ldd /usr/bin/elfspe

It may point to a 32bit libspe2 which you may not run. I *assume* that
your elfspe binary is 64bit while the libspe2 library is 32bit.
Yellow dog ships 32bit user land and a few libs in order to run 64bit
apps (like gdb).
If you want to continue using 64bit userland you should recompile
libspe2 which is available on sf [1].
