POSIX-style execute permission isn't a Windows concept, so it was
fortuitous this ever worked. One possibility is that Cygwin was
involved, and a Cygwin emulation got set when tar unpacked the file and
converted back to the tar representation when Cygwin tar produced the
tarball. (The tar in Rtools is a fixed version of Cygwin tar, fixed to
use Windows file paths.)
What are those screen shots of?
R 2.5.2 was a very long time ago. A recent change is
• R CMD build by default uses the internal method of tar() to
prepare the tarball. This is more likely to produce a tarball
compatible with R CMD INSTALL and R CMD check: an external tar
program, including options, can be specified _via_ the
environment variable R_BUILD_TAR.
Can you try using an external tar? (Using the internal tar on Windows
was first trialled in 2.15.3.)
