Could you add the actual calling code that you use when you get this exception, as well as mentioning on which target platforms this would need to run (webplayer, standalone only etc).

After LOTS of research and testing (and hair pulling, and begging), my opinion is to use DotNetZip. You need to copy some .dlls out of the mono framework to get it to work with built .exes.

Here is my Q that describes this: http://answers.unity3d.com/questions/10650/whats-the-best-way-to-implement-file-compression

You know, this is the top google search result for "unity monoposixhelper" at the moment. This snarky response isn't doing the unity community any favors.
