@chulai Would you be able to take a look on MacOS?

Guys, these are the tests I performed:

1. GoldenDict with ao plugin
   1.1) Copy libmacosx.so to /usr/local/lib/ao/plugins-4/libmacosx.so
   1.2) Try to play some sounds in GoldenDict with the internal player.

Outcome: Works!

2. GoldenDict without ao plugin
   2.1) Delete libmacosx.so from /usr/local/lib/ao/plugins-4/libmacosx.so
   2.2) Try to play some sounds in GoldenDict with the internal player.

Outcome: Doesn't work. Error is "FFmpeg audio player: Cannot find usable audio output device."

3. GoldenDict with patched lib ao (so not to use ao plugin install)
   3.1) Delete libmacosx.so from /usr/local/lib/ao/plugins-4/libmacosx.so
   3.2) Apply pull request Use patched libao in order to support OSX without copying plugins (#295) #377 with timonwong:libao_osx branch and do a full build of GoldenDict.
   3.3) Try to play some sounds in GoldenDict with the internal player.

Outcome: Works!

I ran those tests in 10.6.8 Snow Leopard, 10.7.3 Lion and Mountain Lion and I got all the same results.

Is that enough?

It works for me as well, so it seems ready to merge.

I just updated the Spanish locale. If we can merge this I'd like to build a new EA build for Mac OS X soon.
