 I am not really sure what happened on your system. I can correctly build
 Boost on my Win7 system without having Python on the path at all (without
 building up Boost Python, ofcourse) so I do not really know what Python
 dependency you are talking about.

 The only Python dependency I am aware of is in the Boost Python library
 and some internal testing scripts. Could you help find any others?

 Actually, I'm quite fond of Python. :-) But, as I said before, I'm not
 actually sure what Python dependency you're referring to here...

 However - could you try out the corrected source file I attached to this
 ticked and see if it fixes the issue? Just checkout Boost Build revision
 80313, patch it with the attached file, build Boost Jam from there (run
 the 'tools/build/v2/engine/build.sh gcc' script) and then use the built
 Boost Jam executable to install the Boost libraries.
