[Python.NET] How to compile Python for .Net in VS2010 and .NET 4?

[brad at fie.us]

Your python was built with UCS2 unicode support, rather than UCS4.  There is a compiler directive in the VS project of pythonnet for that.  Pythons that are compiled UCS2 and UCS4 respectively, are binary incompatible with one another.  Hence, pythonnet cannot target both at the same time.

However, it requires Mono.Unix reference in error message. so I installed mono(mono-2.10.9-gtksharp-2.12.11-win32-0.exe from http://www.go-mono.com/mono-downloads/download.html. And added Mono.Posix.dll as reference, and compiled again, got error. FYI, I selected build option as DebugWin/x86.
