[IronPython] Fresh IronPython installation not working.

[Hernán Martínez Foffani]

After a clean installation of IronPython 2.0 Beta 5, it gives the
following exception just by calling the interpreter.
The odd thing is that it only happens in one new PC (Spanish XP
SP3, .NET Frameworks 1.0.3705, 1.1.4322, 2.0.50727, 3.0). We've been
using IronPython in other similar computers without any problems. I
guess it has to do with a bad configuration in that PC but I'm clueless.
Any hint?

Regards,
-Hernán.
