: Screamer is a system for allowing nondeterministic computations in LISP.

I don't know anything about screamer, but the above message usually
indicates that clisp wasn't able to locate a file it wants to access. Maybe
the problem is that clisp files use the .lsp extension, not the often used
lisp extension to denote lisp source files. Try renaming all the *.lisp
files to *.lsp.
