First, thank you for your report.

Parallel building of several ports is not supported. For simple reasons -
conflicting access to same resources. For example is one port is rebuilding
linker hint file and second port is trying to link at the same moment,
second port will fail with message about missing library, as you seen.

Port infrastructure itself is not ready for parallel builds, there is no
locking of /var/db/pkg data, and nothing is tracking that chains of dependencies
are compiled in correct order.

Now what could be done is parallel building inside single port, if given
software allows it. For proposal on this issue please see
