When a port gets built, the ports system looks for and installs any
missing dependencies. As several different ports may satisfy a
dependency the ports system looks for the functionality, a key
executable, library etc, rather than a specific installed package.

The error you see can occur when the port thinks it need to install
a missing dependency port, but that install fails due to an existing
entry in /var/db/pkg. This happens either because the appropriate
files are missing or the port is looking for the wrong thing in the
first place. It may be due to a mistake by the port maintainer or, more
likely, a failure to deal with UPDATING entries correctly.
