Mercurial clone of python? Haha I am not sure what that is. My unix also won't recognize "hg", and will ignore "import --no-commit issue-13057.diff".

I went ahead to edit configure file. Partially understanding the content of .diff file, I edited the configure and here is the difference...

I will try to rebuild now...

$ diff configure.original configure
