You should be using the first one, but from the error message, viz.

> >> "-hex: No such file or directory"

it seems like you are using the second, or anyway some `hexl' program
that does not understand the -hex switch that Emacs passes to it.
Please show the value of your Emacs's exec-path, with "M-: exec-path RET".
