About package review and mismatching md5sums

[P J P]

   Hi! :)


One of the package review guideline says

===
MUST: The sources used to build the package must match the 
upstream source, as provided in the spec URL. Reviewers should use 
md5sum for this task.
===


Past couple of days, I've been reviewing the python grapefruit package 


  at - https://bugzilla.redhat.com/show_bug.cgi?id=716808

and the thing is, the spec file provides an - $ svn export -r 31 ... - command to pull the sources and create a tarball using $ tar -czvf ...

But as it turns out, it seems, if you create a tarball from the *very same* sources on two different machines, they don't match. As in the md5sum for the two tarball differs.

Please try this simple test

=====

$ echo 'Hello, world' > 1
$ tar -cjf 1.tar.bz2 1

$ scp 1.tar.bz2 to a different machine.

$ ssh to that same machine
$ tar -xjf 1.tar.bz2 -C .
$ tar -cjf 2.tar.bz2 1

$ md5sum 1.tar.bz2 2.tar.bz2
d67ea3dac09ed7eee310d9846ecdd879  1.tar.bz2
d4b716716f3cf48139c4112719538513  2.tar.bz2

=====

Could someone suggest how to fix this glitch? Or the guideline above??


Thank you.
