@Kyle
I would have suggested that!  But the way I took the OP's full question in
*SO* was "it *might* be on the PATH already, I don't know, so I just want
to add something to the PATH to be sure just for this one-time spawn, and
then let the OS find it somewhere for sure.  And, I don't fancy doing the
PATH search myself from code". :)
