Usually a library development package Provides: and Replaces:
such package to avoid installing several versions of development
package for the same library.

libfoo1-dev Provides/Conflicts: libfoo-dev
libfoo2-dev Provides/Conflicts: libfoo-dev


So that libfoo1-dev and libfoo2-dev (which both provide
libfoo.so symlink) will not be 
installed at the same time.



You can read libpkg-guide if you need more information.
