This is not what the OP asked for IIRC.  He wanted to modify the 
environment of a process started from his Ruby program not the program's 
own environment.  This question was likely inspired by the POSIX C 
function /execle/.

It will likely work but also affect the program's own environment as 
well as that of all subsequent started sub programs.

Kind regards
