Python 2.7.4 Released (but I had touble updating the port)

[Pedro F. Giffuni]

Hello guys;

There is a new bugfix release in the 27 series with hundreds of 
bugfixes:
http://hg.python.org/cpython/file/9290822f2280/Misc/NEWS

I gave a try at updating the python27 port and it was rather easy to 
get started (almost all patches apply cleanly) but I get this problem
 when building:

...
cc -c -fno-strict-aliasing -O2 -fno-strict-aliasing -pipe -march=nocona 
-DNDEBUG -O2 -fno-strict-aliasing -pipe -march=nocona  -I. -IInclude 
-I./../Include -fPIC -DPy_BUILD_CORE -o Python/Python-ast.o 
Python/Python-ast.c
cc: Python/Python-ast.c: No such file or directory
cc: No input files specified
*** [Python/Python-ast.o] Error code 1

The file actually exists.

I went ahead and reported the issue upstream (Issue17649) but it is
irreproducible in their buildbot and the problem is not really theirs:
it looks like the hacks that we do to stop some modules from building
and the environment used to build the code out-of-tree don't get along
very well.

Perhaps someone here knows the port well enough to provide a fix?
I guess it should be possible to modify the makefile to skip generating
that file since it exists already but that's not very clean ;).

Regards,

Pedro.
