Here's how it's supposed to work.
In the "help" directory inside the LabVIEW directory is a shell script called "hyperhelp". This shell script should have execute permissions for LabVIEW to call it. (E.g., "chmod 755 hyperhelp".) In fact, you should be able to invoke the script directly from the UNIX command line. You might try it and see if it returns a meaningful error.
The shell script sets up some environment variables and calls an executable in the "help/bin" directory. This executable is also called "hyperhelp". It should also have execute permissions. You should be able to run it directly, too.
Anyway, I suspect something is wrong with one or the other file, and hopefully if you run them directly, you'll find out what the problem is.
