There is an interactive `setenv' command which asks for an environment
variable and its value, but in this case maybe you will find more
practical to do this:
* switch to the *Scratch* buffer.
* type:
(setenv "PATH" (concat "/your/path/goes/here:" (getenv "PATH")))
* don't forget the colon!
* with the cursor after the last closing parenthesis, type C-x C-e
Done. You now have /your/path/goes/here as the first entry of PATH.
