configure works, but make immediately fails:

I'm closing this as invalid/duplicate, but I'm sure this isn't the last time we'll get this report.  It would be nice if we could think of a way to improve the situation.

duplicate of http://bugs.python.org/issue12152

I should have mentioned the bug number in the body, thanks for adding that.  FYI, the bug number also appears in the 'superseder' field, and (more interesting to you in this context) if you just say, for example, 
issue 12152 or #12152 roundup will automatically turn it into a link.

here's a patch that fixes the issue.
You can use hg import to apply it to your hg repo, autoconf has to be run afterwards.

The log message is:

    disable ASDLGEN if hg won't work, or if python is not installed.
    
    This change makes configure check for
    - the existence of a hg repository
    - the hg executable itself
    - the python executable
    
    Running $(srcdir)/Parser/asdl_c.py (i.e. ASDLGEN) will fail if any of
    the above prerequisites is missing, so we now disable it instead.
    
    Also see http://bugs.python.org/issue12225 and
    http://bugs.python.org/issue12152

I've setup a hg repo on bitbucket with that patch.

Check for python executable is not complete . What about if system has only version 3+ installed ?

Then hg can't possibly be installed either.

As the OP notes, autoconf needs to be run to update `configure` and those changes needs to be pushed as well so that 'configure.in' and 'configure' are in sync again.

The shebang in Parser/asdl_c.py reads '#! /usr/bin/env python'.
That is what the makefile is calling. So unless you want to change the
Makefile too and start calling '@PYTHON@ Parser/asdl_c.py', I think the
check is rather complete.
