Is this a typo or did you really mean /private/vars?  That is, did your =
create a =E2=80=9Cvars=E2=80=9D directory under /private at some point =
in the past (pre-Yosemite)?  The usual directory there would be /var

In any case, the whole /private directory tree is now part of the SIP =
(System Integrity Protection) system under Yosemite, and to open and =
manipulate files there you will have to either turn SIP off or jump =
through hoops.  If you do a ls -al in /private, you will see that var is

	drwxr-xr-x 29 root wheel 986 Oct 23 11:20 var

note the =E2=80=9Croot=E2=80=9D and =E2=80=9Cwheel=E2=80=9D owner and =
group names. I=E2=80=99d suggest moving your tests to a different =
directory that isn=E2=80=99t part of SIP, and debug there. If you MUST =
work under /private, you will have your work cut out for you.
