Installing simulink support packages on MacOSX

I'm trying to install the simulink support packages for raspberry pi, arduino, etc and am running into a major hurdle. The install for all packages fails at a file copy.

cp -r -p -f '/Applications/MATLAB_R2015a.app/toolbox/shared/hwconnectinstaller/resources/license.txt' '/Users/lane/Documents/MATLAB/SupportPackages/R2015a/arduinobase/license.txt'

The reason the cp fails is because the target directory does not exist and apparently the cp command on OSX doesn't create the parent directories if they do not exist. I tried to be clever and create the directory prior to running the installer, but it looks as if the first step of the installer is to remove it. I'm not really sure where to go from here.

I've been searching the forums and consulted with Google, without even getting close to what describes this issue. Though I can't imagine I'm the only person experiencing this, I'm not having success in dredging up a solution. Any assistance is appreciated.

I have exactly the same issue with installing usbwebcams package on Matlab 2015b. Too bad I haven't been able to find any other related post after googling around for a while
