No. Let's assume you installed png-1.4 and a bunch of packages that
depend on it. Let's also assume the binary repository was rebuild with
newer png-1.5 (all packages that depend on png were rebuilt!) which is
NOT backward compatible with png-1.4. This kind of things may happen if
you switch from 2012Q4 to 2013Q1, for example.
In this example, if you try to update png package with the following command
nih update png
nih will automatically update ALL png's dependent packages based on
REQUIRES/PROVIDES information provided by pkg_summary(5). So, there are
no issues of this type in "nih".
If you install png via pkg_add (it ignores REQUIRES/PROVIDES), you'll
have a problem which can easily be identified with a help of
nih verify -l
Revdumps is a method for bulk builds utilities, not for package managers.
