The port sometimes doesn't build when FORCE_MAKE_JOBS is defined. Fix: Patch attached with submission follows:
Responsible Changed From-To: freebsd-ports-bugs->danfe Over to maintainer (via the GNATS Auto Assign Tool)
Responsible Changed From-To: danfe->pgollucci maintainer timeout (danfe ; 32 days)
Responsible Changed From-To: pgollucci->danfe back to danfe
State Changed From-To: open->closed Port should be safe now, thanks for report.
