It's defunct, and removed in a doc patch coming soon.

The problem is that try-foreign-library-alternatives depends on the
return value of load-foreign-library, which is unspecified.  I believe
luis said on IRC that it was supposed to return non-nil on success,
which I implemented in unified diff
http://csserver.evansville.edu/~sc87/cffi/load-foreign-library-answers-nil.patch

The other possibility, changing t-f-l-a to ignore l-f-l's return value,
is implemented in darcs patch tfla-success.patch in the same directory.

Thanks also for the kind word on the tutorial.
