[ESS] install location of stata on linux

[Jim Maas]

I'm attempting to use the ESS stata mode to run a file but get this 
error in response to M-x stata

/usr/bin/env: stata: No such file or directory

my installation of stata is actually  in

/opt/stata12/

and I've added this to the path so both terminal and graphical stata 
start fine from a terminal window.

Could anyone tell me how to configure emacs/ess to look for stata in 
this directory?

Thanks

J
