libMonoPosixHelper.dylib has a copy of minzip for use in System.IO.Packaging/etc.

The System.IO.Packaging namespace is in WindowsBase.dll:

	http://msdn.microsoft.com/en-us/library/system.io.packaging.package(v=vs.110).aspx
> Assembly:  WindowsBase (in WindowsBase.dll)

WindowsBase.dll, in turn, is installed:

	$ find /Library/Frameworks/Mono.framework/Libraries/ -name WindowsBase.dll
	/Library/Frameworks/Mono.framework/Libraries//mono/2.0/WindowsBase.dll
	/Library/Frameworks/Mono.framework/Libraries//mono/4.0/WindowsBase.dll
	/Library/Frameworks/Mono.framework/Libraries//mono/4.5/WindowsBase.dll
	/Library/Frameworks/Mono.framework/Libraries//mono/gac/WindowsBase/3.0.0.0__31bf3856ad364e35/WindowsBase.dll
	/Library/Frameworks/Mono.framework/Libraries//mono/gac/WindowsBase/4.0.0.0__31bf3856ad364e35/WindowsBase.dll

Using the assembly Works For Me™:

	$ csharp -r:WindowsBase.dll
	csharp> using System.IO.Packaging;
	csharp> Package p = null;

OK, not a great example, but it shows that the assembly, namespace, and type were found by the compiler...

What would be helpful is if you provided your sample code and the corresponding error message. AFAIK, Mono should be able to find libMonoPosixHelper.dylib, so I don't understand the error you're seeing.
