Hi Lucio,
In the "development" section for Synaptics, you will see g++4.1 and
perhaps some other versions. You will also note that it will show
versions for gcc, I believe that you need to install the same version
number (in this case 4.1, but you should check what gcc you have installed).
The compile that I did is generic, that is I did not make any
architecture specific settings. So I would hope that this would run on a
similar linux installation.

My system actually deinstalled X11 and many basilar components. I tried reinstalling them later on to fix the problem, but no way to solve it fastly. In the meanwhile someone elses told me : why don't yuo use binaries? :-P So, I preferred that very fast way ;o)
