tar warnings in R-3.0.2 RC when R is installed by a different (non-root) user

The issue is not the ownership (uname) but the uid.  A tarball can only store
uids up to 'nobody' (usually 32767), and certainly larger ones cannot be
unpacked portably.

The warnings did not occur before, but the tarball produced could cause problems
when unpacking with other tools.

Hi,

I created a package as follows:

a = 1
package.skeleton()

Then I got the following output when building the package:

* checking for file ?anRpackage/DESCRIPTION? ... OK
* preparing ?anRpackage?:
* checking DESCRIPTION meta-information ... OK
* checking for LF line-endings in source and make files
* checking for empty or unneeded directories
* looking to see if a ?data/datalist? file should be added
* building ?anRpackage_1.0.tar.gz?

One thing to note is that I am logged in as 'pkgbuild' and R was installed by
the user 'biocbuild'. I explicitly point to the R that was installed by
'biocbuild' when building the package above. (I used the command
"~biocbuild/bbs-2.13-bioc/R/bin/R CMD build anRpackage").

There doesn't seem to be anything wrong with the ownership of the files in
anRpackage:

$ ls -lR anRpackage
anRpackage:

These warnings did not appear with an earlier version of R-patched (r63824).

Thanks,
Dan
