Installing FhGFS leads to little glitches. I am installing on Debian 7.0 running XQuartz on Mac OS X.

• to avoid the XTEST error message when starting the Java GUI, follow the instructions on http://xquartz.macosforge.org/trac/ticket/414 and enter defaults write org.macosforge.xquartz.X11 enable_test_extensions -bool yes in a terminal window before starting the GUI
• if you are using a proxy, be sure to define it in /etc/environment before starting the admon process or else the automatic wget downloads will fail
