[Python-Dev] Unable to build old version from hg.python.org

[Vinay Sajip]

I want to maintain several working copies, as sometimes I have to make bugfix
changes across several revisions. Since we are supposed to use forward-porting,
I tried to set up a 2.5 clone, but building from it fails with a "Fatal Python
error: subversion keywords missing".

What I did (in ~/projects/python):

hg clone ssh://hg@hg.python.org/cpython default
hg clone default 2.5
cd 2.5
hg update 2.5
./configure
make

Failing command:

-------------------------------------

BTW, this is happening on my Ubuntu Jaunty machine which I have been using for
many months with the Subversion repository.

Am I doing something wrong?
