[IronPython] What version of CLR is required to build latest IronPython sources?

[Dan Eloff]

I opened the Visual Studio 2008 Command Prompt and typed clrver:

c:\Program Files (x86)\Microsoft Visual Studio 9.0\VC>clrver
Versions installed on the machine:
v2.0.50727

Is this good enough, or do I need to install a different CLR version
to build IronPython? (I'm getting build errors, so perhaps this is the
reason)
