I've seen this -L../common/src, but it did not picked up the static library with the -luclmmbase

I actually used the OpenBSD ports infrastructure to get it installed.

There is openal in the ports tree, it seems to support sndio. But as it seems, the sndio patch did not made it upstream, since its still bundled in the port.

Is there maybe a bug report in the track where I could grab the patch?
