On my own machine I have issues while using gnuwin32 tar for
extraction. I encounter *no* errors while using Cygwin tar (See the
enclosed logs down below)

While running the following command:
- tar -xOf org-20101101.tar org-20101101/org-pkg.el

the error reporter in my setup is:
,---- [error with gnuwin32 tar on my machine]
| "tar: Header contains "\200\000\000\000\000'\347\033" where octal uid_t
| value expected"

while the error encountered in your setup is:
,---- [error with gnuwin32 as reported by you]
| "tar: Archive value 297315 is out of gid_t range 0..65535"

The thing that seems common in both these errors is that it relates to
the username and groupnames (uid_t and gid_t). This has something to do
with how tar archives are created on build machine.

I don't have much experience with packaging. I am dumping my analysis
hoping that someone would offer a quick fix for the problem.

For the sake of reference, here is how the elpa archives are built.

| pkg:
|         [...]
|       rm -rf org-$(PKG_TAG) org-$(PKG_TAG).tar
|       $(MKDIR) org-$(PKG_TAG)
|       cp -r $(PKG_FILES) org-$(PKG_TAG)
|       echo "(define-package \"org\" \"$(PKG_TAG)\" \"$(PKG_DOC)\" 
$(PKG_REQ))" > org-$(PKG_TAG)/org-pkg.el
|       tar cf org-$(PKG_TAG).tar org-$(PKG_TAG) --remove-files
