--- Comment #4 from paulo i30817@gmail.com 2011-09-08 13:49:05 CDT --- I'm closing this bug - it's invalid and due to installing BWP in a virtualbox windows with a shared filesystem with ubuntu.
One of the programs needed to install failed writing some files on the shared filesystem due to a (buggy) driver.
I think it will work if i do it on the image file (though it will probably be much slower).
