This is Beta4 for 1.0 Release.
A Slackware based system is needed in order to use QTGZManager, as well as Qt 4.4.x libraries (http://www.slacky.eu has this package). 

To compile the sources you can do the following:

cd <path to qtgzmanager>/src/
<path to qt4/bin/qmake 
make

The binary will be on ./bin/qtgzmanager.

Enjoy!
