Just to confirm it works if you use export in the same shell process, i.e.:
system('echo Old path: $PATH; which jags; export PATH="/usr/local/bin:$PATH";
echo New path: $PATH; which jags’)
Not an ideal solution of course, as every call to system() needs to be modified
… but at least it does work (for me at least).
