Solutions you can use:

1. Modify myapp so it knows where to find its libraries. e.g. it could contain
        require '/etc/myconf'
   where /etc/myconf.rb contains $:.unshift("/path/to/lib")

2. set RUBYLIB so the child process knows where to look for its libraries

    ENV["RUBYLIB"]="../lib"
    system("myapp")

3. since it's a Ruby program, you could run it in your existing Ruby
   interpreter:

    $:.unshift("../lib")
    load("myapp",true)
