eyelink mex error

I've just installed the psychtoolbox on a new machine and when I type Eyelink I get the following error:

>> Eyelink
??? Invalid MEX-file '/Applications/Psychtoolbox/PsychHardware/EyelinkToolbox/EyelinkBasic/Eyelink.mexmaci': dlopen(/Applications/Psychtoolbox/PsychHardware/EyelinkToolbox/EyelinkBasic/Eyelink.mexmaci, 1): Library not loaded: @executable_path/../Frameworks/eyelink_core..framework/Versions/A/eyelink_core
Referenced from: /Applications/Psychtoolbox/PsychHardware/EyelinkToolbox/EyelinkBasic/Eyelink.mexmaci
Reason: image not found.

But if I type help Eyelink, I get the usual help screen. I did an update of Psychtoolbox and I'm using this system:
