If you just downloaded the function dir2 and place it in a location whose path is added to the system, it's bound not to work. Usually, built-in functions make use of some others functions (mex-files quite often). If you don't have those other functions in your system, your function will not work. In your case, it seems you are encountering an issue with a dir2_mex.c function.
