Under normal conditions, libfoo-dev should work. If say your package
gets built with libfoo1 by the autobuilders, and then libfoo2 is
released and the maintainer says "libfoo1 is going away, rebuild your
packages", then you may need to do something.
Most people feel that not keeping older soname libs around for a certain
period is a bad idea, just for this reason. You as the package builder
shouldn't have to worry about it.
