It seems your compiled code is trying to load a file
with the export declaration as source code (the evaluator
available at run-time does only support basic R5RS syntax
and not (among others) "declare".

Can you provide the exact compilation instructions you
used to build cackle-base.so?

"load-library" is intended to load a shared object (dynamic library,
most of the time) that includes several modules. For example the
core library units in the chicken library (srfi-1, utils, etc.) are loaded
that way. "load-library" can invoke a given entry-point function.
If you compile a file into a .so using -shared, then you just use
"load" or "require" or "require-extension", which invokes the
main entry-point. "load-library" is mostly useful if you combine multiple
shared objects into a single library.
