R.Net Initialization error on Mac resolved by starting from Xamarin from terminal

This is more of a workaround for those who might have the same issue as me than a serious issue, although if someone can explain to me how to resolve the underlying issue that would be great as well. I followed the steps in the wiki to set up RProvider for Mac, except I use the homebrew provided mono and R which are both 64bit by default.

When launching Xamarin from the Launchpad I get the following error:

```
The type provider 'RProvider.RProvider' reported an error: The type provider constructor has thrown an exception: Initialization of R.NET failed
```

But when launching Xamarin from the terminal using:

```
open -n /Applications/Xamarin\ Studio.app/
```

Everything works fine.
