I suspect you are having some path issues.  The PHP script probably isn't
"aware" of how to find the myprogram.rb script.  Try using the full path
to the Ruby script there.

Then . . . assuming that works, you might want to look into how you can
make path handling a little more robust and flexible.  First step, of
course, is just making sure that the Ruby program will work in this
context, and you should be able to do it with something like:

    system('ruby /absolute/path/to/myprogram.rb');

It's probably related to the execution context of your PHP script (what
it "thinks" is its current working directory) and the location of your
Ruby program.

That should not affect the execution of a Ruby script via PHP's system()
function, as far as I'm aware.
