I run into the same problem. It is a strange Matlab behaviour, in my case it is trying to compile both, the mac and the unix version because isunix is true for OSX as well. If you change line 64 from

 if isunix

to

if isunix && ~ismac

it might work.

I tried @groakat methods, it didn't work for me. Anyone has other methods?

[groakat]

Do you get any error?

@groakat , I set the lib path wrongly :P, now it works. Thank you~
