Dear all,

I need to cross compile a python extension using boost.build. I have 
Python 2.6 (32 and 64 Bit) and Python 2.7 (64 Bit) installed on my 
computer. I compiled boost with Python 2.6 (32Bit).

My goal is to compile the python extension for Python 2.7 (64Bit).

The problem is that it does not try to not find the python27.lib. Is 
there a way to do this without re-compiling Boost with Python 2.7?

Thanks,
Ronny
