It's not a problem with apt-get nor with aptitude. We have fixed this bug on Debian with graphicsmagick version 1.1.11-2:
* debian/control: ImageMagick's -dev packages have stopped providing virtual, unversioned aliases, recently. Add explicit Conflicts and Replaces on the versioned package names libmagick9-dev and libmagick++9-dev in the -compat-dev package.
