No idea. GCC is a quite complicated mess. That is why I prefer not to 
experiment with its manual installations. People did that already and 
packaged it for you.

GNAT is a part of GCC, no less than other front-ends.

GNAT GPL comes once a year.

You should have enabled the hardware acceleration in the machine 
configuration (Machine settings -> Display -> Enable 3D Acceleration), add 
video memory etc. And if you are using guest graphics then do it in the 
steamless mode rather than in the windowed one. Though all this is not 
Debian problems (it has lots of its own).

And know what, the above is IMO a wrong way to use the virtual machine 
anyway. Are you under Windows? Install Xming (that is an X11 server for 
Windows). Log into the virtual machine using SSH with X11 tunneling. Start 
gnome-terminal with the server of the host machine. Run GPS and enjoy life.
