I might be three steps behind you here, but does "mpirun <args> pwd" show that all your launched processes are running in the same directory as the mpirun command? I assume that "mpirun <args> env" would show that your PATH variable is being passed along correctly, since you don't have any problems with absolute paths. In any event, is PATH=$PWD/dir/bin not an option?
Seems to me that this last would be good practice for location-sensitive launches in general, though I do tend to miss things.
