Thanks! That was the problem. I was also having trouble loading another library, located in /usr/local/lib. That doesn't seem to be in the default library search path on my debian box, though it is on my OS-X box. Or at least that is my guess based on this working (in the context of define-foreign-library):

(:unix "/usr/local/lib/libplplotd.so")

and this not working:

(:unix "libplplot")

However, maybe I didn't set something up correctly?
For SBCL, does CFFI use sb-alien:load-shared-object to load the library?
