The `ffi/unsafe/objc' library does not depend on `racket/gui/base'. But `racket/gui/base' initializes `NS...' libraries in various ways. In particular, it causes the "Foundation" framework to be loaded, which is needed for `(import-class NSAutoreleasePool)'.
You may want to use `ffi/unsafe/nsalloc'.
