It's just that the XSUB code is supposed to make the actual call to the library, yes?

No. You're confused. h2xs just generates scaffolding. It doesn't compile code, it doesn't link code. It has nothing to do with the error. ldd shows you libtwintree isn't being loaded by TwinTree, probably because libtwintree exports nothing. You need to examine what the compiler/linker are doing before/during make.
