Change the way we check the required version of the dependency (#428)

There are still some cases for false negative where the direct
constrant is ok and other indirect dependency has a problem.

Although the issue is not completely fixed, this logic change allows
more legitimate cases which has been failing with the previous code.

It will alleviate #426
