[argyllcms] Dispcal fails

I'm finally getting my feet wet with dispcal. But, so far, my work is not
crowned with success :(

Here's my command line:

> dispcal -v -a -m -i94 -yl -t5000 -b95 -gl -e caltest

And this is what I'm getting:

> Setting up the instrument
> Offset calibration:
> Place instrument on a dark surface.
> Hit Esc to skip, any other key to start calibration:
> Offset calibration successful
> The instrument can be removed from the dark surface.
> Setting up the instrument
> RegisterProcess failed (error = -50)
> Abort trap

I can't get pass that RegisterProcess error?

I'm on MacOSX.4.9 with V0.60.
