It returns T.

However, (cffi-sys::%load-foreign-library "/usr/local/lib/libgthread-2.0.so")
fails with the following:

Error opening shared object "/usr/local/lib/libgthread-2.0.so":
   /usr/local/lib/libgthread-2.0.so: Undefined symbol "pthread_attr_destroy".
    [Condition of type SIMPLE-ERROR]

So this indicates that it's CFFI (or perhaps something in the way
FreeBSD sets these libraries up)?
