Ok. I've updated release.py to do the dirty work in 65708.

[issue3499] Python 2.6 requires pre-installed Python to build

This happened in my fresh unpack of the 3.0b2 tarball, as well.

Touching merely Include/Python-ast.h satisfied the dependency, and I did
not have to touch Python-ast.c.  Is the particular grammar-rebuild rule
needed for production tarballs anyway?  I can't think the majority of
people downloading the package want to start hacking the grammar right away.

It should be simple to modify release.py to touch these files. Barry,
I'm on vacation now, but I should be able to do this before you spin the
releases.

[issue3499] Python 2.6 requires pre-installed Python to build

As work-around, you can untar the source tarball and then touch the
files in question:

touch Include/Python-ast.h
touch Python/Python-ast.c

[issue3499] Python 2.6 requires pre-installed Python to build

[Marc-Andre Lemburg]

New submission from Marc-Andre Lemburg <[EMAIL PROTECTED]>:

Here's the "make -d" output:

 Prerequisite `Parser/Python.asdl' is older than target
`Include/Python-ast.h'.
 Prerequisite `Parser/asdl.py' is older than target
`Include/Python-ast.h'.
 Prerequisite `Parser/asdl_c.py' is newer than target
`Include/Python-ast.h'.
Must remake target `Include/Python-ast.h'.
./Parser/asdl_c.py -h ./Include ./Parser/Python.asdl
/usr/bin/env: No such file or directory

And these are the file times:

orig/Python-2.6b2> ls -l Include/Python-ast.h
-rw-r--r-- 1 lemburg users 20081 2008-03-30 08:40 Include/Python-ast.h
orig/Python-2.6b2> ls -l Parser/asdl*
-rw-r--r-- 1 lemburg users 11306 2006-03-01 23:49 Parser/asdl.py
-rwxr-xr-x 1 lemburg users 39771 2008-06-09 06:58 Parser/asdl_c.py

Because Python-ast.h is older than the script used for generating it
(asdl_c.py), it always tries to rebuild the .h file. Since this requires
Python to be installed, it fails on a machine that doesn't always have
an existing Python binary installed.

This happens in both 2.6b1 and 2.6b2.

I guess the release process should make sure that the Python-ast.h and
Python-ast.c are always newer than the scripts used to build them.
