clisp repl requires ffcall to run but is not dependent to it
pacman -Rs clisp ffcall and
pacman -Syu clisp. Now run clisp, you'll get the following error:
$ clisp /usr/lib/clisp-2.49.93+/base/lisp.run: error while loading shared libraries: libffcall.so.0: cannot open shared object file: No such file or directory
ffcallresolves the problem. Person have to install
ffcallperself, it's not a dependency of clisp package.
