[Rd] make check fails 1.7.1 with R-release patch in regression tests (PR#3868)

[Kevin B. Hendricks]

Hi Peter,

Thanks for your response.

I tracked it down to (info <-file.info(".")) hanging and then started checking 
the obvious as to what permissions that "tests" had and soon found out that 
everything was quite messed up (I had forgot to chown the files after 
unpacking them).

Once I cleaned that up and changed owership to a valid user id the hangs went 
away.

So please close this as user stupidiity on my part.  I simply forgot that tar 
keeps old user ids when unpacking and that I need to fix that myself before 
patching and building.

Thanks gain for your fast responses!

Kevin
