On CMUCL, the uffi:load-foreign-library function attempts to use sys::load-object-file to load .so files (rather than falling back to alien:load-foreign as it does for other types). However, unlike alien:load-foreign, sys::load-object-file reports errors (e.g., failure to find the library in question) by returning nil. UFFI ignores this return value (resumably assuming that it would signal an error), and assumes it succeeded.
The specification for load-foreign-library (http://uffi.b9.com/manual/load-foreign-library.html) states that the function will return NIL if the library was not able to be loaded. Thus, the current code correctly follows the specification for this particular case. Kevin
