gcc to build RISC OS

I’m supposed to do this:

ro-path is a script that redirects calls to host tools like gcc to ones that build for RISC OS. For instance:

$ /home/riscos/env/ro-path ./build-me.sh

but, I have an error executing this command:

kaizen@Rk:~$ /home/kaizen/gccsdk/env/ro-path ./build-me.sh

/home/kaizen/gccsdk/env/ro-path: line 27: ./build-me.sh: No such file or directory

can I please know what might be the mistake?
