 The whole purpose of the original split of libao was to avoid
 having build-time options, so this is just going backwards.
 
 wiz@'s suggestion (merging libao-sun and libao-oss again into
 libao), is a possible solution to have everything working out
 of the box again, although I don't like it much.  I can live with it
 because it doesn't add extra dependencies on most systems,
 but I like to not install oss stuff if possible.
 
 Though... I just had another idea.  In libao's buildlink file, we'd
 add an extra dependency of the form libao-*:../../audio/libao-oss
 (not sure if the wildcard there could DTRT, but something else
 probably will).  That is, a dependency that accepts any plugin
 and defaults to oss.  This way, whenever you install an app that
 uses libao, libao-oss will be installed iff you hadn't installed any
 other plugin by hand before.  This is binary friendly and avoids
 options.
 
 Do you think this'd be appropriate?
