Port update for sysutils/rdiff-backup

[Sven Willenberger]

I am curious as to how to go about getting the latest version of
rdiff-backup [http://rdiff-backup.stanford.edu/] (0.12.6 - released 2
Nov 2003) into the ports tree? For example how does one find the current
maintainer of the port? (I cannot see that information on the cvs tree)
or should this request be in the form of a PR ? The program compiles
from scratch (and works fine with the 0.12.3 setup.py patch) and runs
fine.
