Is the path where qsub is located in the search path of the shell
actually used by the Ruby system command? Have a look at:

   system("echo $PATH")

(Different paths compared to your command line might be a login /
non-login / interactive shell issue.)

And how exactly did the command with explicit paths look like?
(It's difficult to locate an error without seeing the used code.)
