There is no easy solution to solve it completely because currently
package dependency is solved in a strict manner including package
names and version numbers, not only existence of specific files.
Creating multiple ports which depend on each software or using
FLAVORS to make it easier is a way to provide packages with every
possible combinations of dependency and let one to choose.
