I found liboss in the ports and checked out the home page http://liboss.sourceforge.net/ .  Is this project dead?  From the home page I can get to OSS, which released the source under a BSD license.  Is this new (the press release is dated January 4, 2008)?  Has it been under a different license?

What is the community feeling towards alsa and oss?  How compatible are they?  How incompatible? 

I have tried to compile asla on darwin/os X, no success.
