Please stop doing that. Your question, and my answer, might be useful
for other people who will later search the archives of c.l.a. See also

Since you're obviously willing to spend as much time as necessary, why
don't you go all the way and  solve your problem once and for all? If
not already done, install Debian Sarge (with GNAT 3.15p and GtkAda 2.4
under GMGPL in the standard paths), then create  a chroot environment
containing Etch or Sid (with GCC 4.1 as the Ada compiler, but no GtkAda
yet). You can create as many chroots as you like. Use debootstrap to
create each of them, then use apt-get inside each chroot to install
packages as usual.

Then, bind-mount your /home directory in each of the chroots, so you
share it between all chroots and the top-level root.

Then, copy your top-level /etc/passwd into each of the chroots, so all
users of the top-level root also exist in the chroots.

Last, use dchroot to allow non-root users to use chroot in a controlled
way.

This solution is less error-prone, quicker, and much much more
maintainable than recompiling everything. I use it myself on my
machine: Etch with gnat 3.15p in the top-level root, Sid (unstable)
with GCC 4.1 in a chroot where I do the Ada transition.
