Comment (by boklm):

 It looks like the update to jessie is causing the diff.

 I did some test rebuilds of tor, openssl and libevent using rbm (the
 current master branch is reproducible on OSX).

 I used the following patch to update to jessie:
 {{{
 diff --git a/rbm.conf b/rbm.conf
 index e206193..0ffdb22 100644
 --- a/rbm.conf
 +++ b/rbm.conf
 @@ -166,7 +166,7 @@ targets:
    torbrowser-osx-x86_64:
      - osx-x86_64

 +    distribution: Debian-8.7
      arch: x86_64
      var:
        osx: 1
 }}}

 And I built the tor compenent using this command:
 {{{
 ./rbm/rbm build tor --target alpha --target torbrowser-osx-x86_64
 }}}

 After doing two builds, cleaning tor, openssl and libevent between the two
 builds, I get a non-matching tor binary:
 https://people.torproject.org/~boklm/tmp/bug_21328/move-jessie/build1/
 https://people.torproject.org/~boklm/tmp/bug_21328/move-jessie/build2/

 In build3 and build4, I did two builds of the tor component only (without
 cleaning openssl and libevent between them), and still get a non-matching
 tor binary:
 https://people.torproject.org/~boklm/tmp/bug_21328/move-jessie/build3/
 https://people.torproject.org/~boklm/tmp/bug_21328/move-jessie/build4/
