Actually, it does; you just don't like the results ;-)

Why do you need these?  Doesn't Emacs find them?

If you paste all this long command line to the shell window, does the
program work then?  (You may need to mirror the slashes for that.)

Also, does the problem go away if you replace "(" with "-(" and ")"
with "-)"?

Does the problem go away if you copy the two programs to a directory
whose name does not include blanks and parentheses, and invoke them
from there?
