Please do not listen to "anon", he obviously knows nothing about
Ubuntu.

The correct answers are:
- aptitude remove gnat gnat-4.3
- no, installing GNAT GPL 2009 does not remove anything previously
installed.
- no, there is nothing wrong with having both gnats installed.

PS. As the main (but not only) maintainer of Ada packages in Debian
(which Ubuntu uses), I am curious to know why you decided to switch
from the Debian packages to GNAT GPL 2009?
