function question yet again

Is it possible to define a function in language 'C' that needs more
libraries to work? I've got a small example of a function that works like a
charm when run against from a binary. However if I put this function inside
the server and execute it I get

ERROR: parser: parse error at or near ""

Not exactly an error message that explains itself. :-)

I have put my function into a shared library to load it, but the library
itself needs other libraries. Is this at all possible?
