E.g. parameters, environment, missing tools.

<h3><a name="MM0000">MM0000: Unexpected error - Please file a bug report at http://bugzilla.xamarin.com</h3>

An unexpected error condition occurred. Please [file a bug report](https://bugzilla.xamarin.com/enter_bug.cgi?product=Xamarin.Mac) with as much information as possible, including:

* Full build logs, with maximum verbosity (e.g. `-v -v -v -v` in the **Additional mmp arguments**);
* A minimal test case that reproduce the error; and
* All version informations

The easiest way to get exact version information is to use the **Xamarin Studio** menu, **About Xamarin Studio** item, **Show Details** button and copy/paste the version informations (you can use the **Copy Information** button).
