Why not? The error message is pretty plain english:
Your link step included the /opt/PPC_X/usr/X11R6/lib/libGLU.so
library, which in turn tried to link against the
libstdc++-libc6.2-2.so.3 library, which was not found by the linker.
This is not a big surprise, as the current version of the ELDK ships

I don't know where you got the /opt/PPC_X/usr/X11R6/lib/libGLU.so
library from. I guess you copied if from a standard PowerPC release.
This is very risky in itself, as it may have been built in a way wich
is incompatible to the ELDK libraries (or are you absolutely sure
that they use the same settings for FPU support and cache line
You should probably rebuild libGLU using the ELDK tools, and link it
against the ELDK provided C/C++ libs.

You must be joking. Of course you have to mind this. It's the root
cause of your problems. And other problems are lurking to hit you as
libstdc++-libc6.2-2.so.3 is most probably incompatible to the ELDK,
