The default compiler on alpha is still gcc 2.95, to the best of my
knowledge. If the autobuilders are using 3.x, this is not reflected in
the default package layout for the architecture.
There is another issue, which is that g++ 2.95 is fairly *broken* on
alphas, and you need to disable optimization by compiling with -O0 to get
most complex C++ code to compile on that arch. For further information
on enabling compile options on an arch-dependent basis, see the rules
file for unixodbc, for example.

I believe the g++ migration is now the only thing we're waiting on for
KDE3.

Various people have stated an intention to make gcc 3.x (for x >= 2) the
default compiler for sarge. If upstream already has a new version of the
package that works with g++ 3.x and KDE3, I wouldn't recommend that you
spend a lot of time trying to get your current version of the package to
work with gcc 3.x -- especially since, on alpha at least, you *can't*
compile Qt-based packages using g++ 3.x.
If you have some time and energy to devote to the matter, I would suggest
talking with the toolchain maintainers about whether there's anything you
could do to help get the gcc 3.x transition moving forward.
