First, you need to make sure you load LLVMDataStructure.so and
poolalloc.so into opt.  You can specify the -load option multiple times,
so you use the first -load option to load LLVMDataStructure.so and the
second -load option to load poolalloc.so.

Second, you need make sure that opt can find both libraries.  Either
specify the complete path to the shared library files or set
LD_LIBRARY_PATH to the directory containing LLVMDataStructure.so and
poolalloc.so.

FYI, libpoolalloc_*_rt.so are the runtime implementations of the pool
allocator memory allocator.  These are linked into your program (either
at the LLVM bytecode or native code level) to provide the pool allocator
runtime functions.

I believe using make VERBOSE=1 will do this.
