You're right.

We could even make it a dependency based on the gcc version.  Wouldn't
that be neat?  Maybe something like this:

|| ( <=gcc-3.3*
	libstdc++-v3 )

For the humor impaired, this was a joke.  Why is it a joke?  Because
you're missing the non-binary packages that this completely breaks.
Want a cool, small example?  Install gcc 3.3, configure it as your
primary compiler, emerge fluxbox, upgrade to gcc 3.4 and remove all
traces of gcc 3.3 and libstdc++-v3, then try running fluxbox.
Basically, vapier got tired of all of the "my $foo package is broken"
bugs because people didn't realize that anything that linked against the
older gcc would *require* being recompiled to work properly.  The
solution?  Add this library by default.
