I'm trying to run bootstrap so that I can build the boost libraries. I've tried with both msvc and mingw. In both cases I get an error saying it can't create the bin.ntx86 folder. I initially tried this from my home directory which has spaces in the path, but I get the same error if I move the boost directory to the root of the drive. 

I've compiled boost on other computers many times so I'm sure there is something wrong with the configuration of the computer, but I don't know where to look to find the problem. Is there a way to get more verbose output from the bootstrap process so I can track down the problem? I've copied my bootstrap.log below. I've tried this with 1.55 and 1.54
