when building without an hg repository present, the build fails with:

./Parser/asdl_c.py -h ../Include ../Parser/Python.asdl
Traceback (most recent call last):

asdl_c.py should not be run during a non-checkout build, since the files it builds should already have been (re)built and checked in by the time a release is rolled.  IIUC The release building script is supposed to ensure the timestamps of the files are such that it won't be called.  What source are you doing the non-checkout build from?

Indeed, Include/Python-ast.c and Python/Python-ast.c should be touched to avoid this.

I'm building a snapshot package on a buildd, where a checkout is used (without the .hg directory). buildds don't have access to the network, and I don't want to package the .hg directory. So I assume I have to create a "release" tarball on my own, and build from that one. iirc I didn't see this behaviour with python3.2 when building pre alpha snapshot packages.

It's true that Python use to be the only dependency for asdl_c.py, but now Mercurial is, too.

And like Benjamin said, it should be enough to touch those two files.  You don't have to actually build a release tarball.

ok, thanks. good enough
