Nirvana and qtranslate and yoast

Dear Zed, someone

I’m using nirvana and am happy. Also, I found here that I could (and have been) use qtranslate for my multilingual website.
Recently, I’ve installed yoast and started looking into it.

Now, I’m faced with the following problem: I can’t translate meta title and description fields. I’ve looked into qtranslate and to yoast and they’re presenting some sort of fix (integration and or fix) solution. I tried installing the fix but noticed no differences and entering the code yoast provided in functions.php led to an error. Later, I tried entering the some code in nirvana child theme but, once again, ended noticing no differences.

This is something indirectly connected to nirvana but, anyways, I was hoping for someone to provide me a clue on how my original problem: how do I translate meta title and description fields? Do I have to start thinking about a change form qtranslate or Yoast (and no, I’m not considering leaving Nirvana)?
