Installing Forticlient SSL on Linux Mint (64 bits)

I need to use this rather crappy VPN client one to connect to a couple of an associate data centers.
These is are the steps to install the Fortigate SSL Client on Linux Mint Maya.
As usual, unpack it and execute the installer:

usul > ./forticlientsslvpn 
./forticlientsslvpn: error while loading shared libraries: \
libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory

It'll fail, so, install the 32 bits libraries:

usul > sudo apt-get install ia32-libs-gtk

Note, selecting 'ia32-libs' instead of 'ia32-libs-gtk'

After this operation, 68.5 MB of additional disk space will be used.
Do you want to continue [Y/n]? Y

Once that is up & done, simply give the installer one more try:

./forticlientsslvpn 
/usr/local/bin/forticlientsslvpn/.//helper//setup.linux.sh: line 11: \
/usr/local/bin/forticlientsslvpn/.//helper/forticlientsslvpn.install.log: Permission denied
/usr/local/bin/forticlientsslvpn/.//helper//setup.linux.sh: line 12: \
xterm: command not found

It'll fail once again, because by default there is no xterm installed on Linux Mint MATE 13.
Edit the file setup.linux.sh, comment the line:

##      xterm -e "$0" 2

And add this line, just below the one commented:

        gnome-terminal -e "$0" 2

Then execute the installer:

./forticlientsslvpn

The first time you execute it there is a splash screen, the reason this thing wanted to use xterm.
After that there might be a menacing pop up informing the installation failed, but its crap, simply continue and be happy.
