Log Message:
dhewm3: partial update to 1.5.4.

1.5.1 does not compile against openal-soft 1.24.1, the current
pkgsrc version. I tried updating to 1.5.4, but it has the same
problem, so I filed an upstream bug report.

So the update work is not lost, commit it, but mark the package as
BROKEN for now.
