Yes, thanks for asking. I will quote Kirill below:

>I fixed the error in "Cache.pm". For the older version of perl, the function "mkdir" required 2 mandatory parameters, but for the latest version of perl (which I used for programming and testing), the second parameter becomes optional. So I just fixed the function call. Please let me know if you notice other compatibility problems.

I will look up my perl version and post that as well... so that may help others as well.

Hope this helps.
