Normally you should compile both wrapper and .c file together into
a shared library, like this:

  csc foo-wrap.scm foo.c -s -o foo.so -J

This should give you a module that you can load into CHICKEN and
run, including the import library. But the definition "foo#foo" is definitely wrong (it should
be just plain "foo"), so the module is unresolved. I will fix this
as soon as possible.
