SyslogAppender "works for me" (tm) but I haven't tried 0.10.x

Steps for troubleshooting:

1) Use some other app to make sure your logging setup is correct. I suggest the 
simple command line logger from the bsdutil / util-linux project:

http://freshmeat.net/projects/util-linux/

2) Use some facility that is working and being used by other apps on the system 
before trying some custom LOCAL_X facility. Combining steps 1 and 2 you should 
be very confident that you are watching the right file before moving on to step 3.

3) Write a simple log4cxx test app and try it. The attached one requires no 
external config and works fine on my systems with log4cxx 0.9.7.
