Er, normally you don't need any Python installed to build Python (be it 3.x or 2.x). Are you sure about this?  I remember needing an existing Python to building Python 2.7 on a new python-less install of FreeBSD a couple of months ago.  But maybe that was just an issue with timestamps on files.  I'll see if I can reproduce.

With a fresh checkout of the release27-maint branch on an Ubuntu 64-bit VM, with /usr/bin/python renamed to /usr/bin/python_not_here, a './configure && make' fails with:

[...] checking for socklen_t... yes checking for build directories... done configure: creating ./config.status config.status: creating Makefile.pre config.status: creating Modules/Setup.config config.status: creating Misc/python.pc config.status: creating Modules/ld_so_aix config.status: creating pyconfig.h creating Modules/Setup creating Modules/Setup.local creating Makefile ./Parser/asdl_c.py -h ./Include ./Parser/Python.asdl /usr/bin/env: python: No such file or directory make: *** [Include/Python-ast.h] Error 127

I think this is the same problem that I saw on the FreeBSD VM.
