If you have $PATH set in your working shell, Hydra should pick it up 
automatically. I'm assuming this is what you are doing:

% export PATH=<path_to_exec>:$PATH

% mpiexec.hydra -f hosts -n 1 a.exec arg1 : -n 1 a.exec arg2 : -n 1
a.exec arg3 : -n 1 a.exec arg4

I just tried this and it seems to work fine.
