$ python2.7 -c 'import xattr'
Traceback (most recent call last):

    import cffi

I fixed the missing dependency in r141108. Wait for the updated port or
just install the port manually:

$ sudo port install --unrequested py27-cffi

We do not have a port for pylibacl. However, OS X does not even use
POSIX ACLs, so I do not know how useful it would be...

I guess we can ignore those.

For the Finder information, rdiff-backup tries to use
Carbon.File.FSSpec, which is no longer supported:

$ python2.7 -c 'import Carbon.File; import MacOS; print
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute 'FSSpec'

These problems should rather be discussed and addressed by rdiff-backup
developers. They are not caused by the packaging, but exist in the
upstream version.

Hope that helps,
