Seeing as PhoeNUX OS' administration utilities and installer are all written 
in Perl Qt, we'll need to chase down this leak since we are not interested in 
porting all the utils and installer over to a compiled language due to the 
need for rapid patching of the application should the need arise. 
Additionally, Python isn't an option for us since most of the developer team 
for PhoeNUX OS do not know it and are fluent in Perl.
