Hi Roumen, Reuben.
I'm going through old open bugs, and I've noticed this one. Is the
problem still present, after the recent updates to the python support?
[SNIP]
on my Ubuntu 12.10 system). I'm sorry, I can't tell whether, as Roumen
suggests, this is an Ubuntu packaging bug, or an automake bug.
It seems to me this is a feature as I found this one:
http://patch-tracker.debian.org/patch/series/view/python2.6/2.6.6-8/distutils-install-layout.diff
OK, thanks for explaining it once again. I can now reproduce the same
issue on Debian. I think this is something we should try to work around,
since we cannot have our installation rules broken by default on both
Debian and Ubuntu ...
Lets say platforms that use the "/posix_local/" installation scheme
instead wrong or broken.
It seems to me that this is the sort of thing the pyconfigure people
ought to know about.
By peeking at their repository, I came up with the minimal patch below,
which should do the trick. Can you verify it works for you as well?
Regards,
Stefano

Subject: [PATCH] python: make installed modules find by default on Debian and
Ubuntu
This change fixes automake bug#10227.
The code used to get the python package directory was wrong for Python 3,
at least on Debian and Ubuntu distributions. In the case the installation
was using the default prefix "/usr/local", python modules were incorrectly
installed in the directory
/usr/local/lib/python3/dist-packages
(which is *not* searched by default), rather than in a directory like
/usr/local/lib/python3.x/dist-packages
which is searched by default.
* m4/python.m4 (AM_PATH_PYTHON): Try to use the 'sysconfig' module if
possible, for better interactions with python 3.x.

Tested with python build from master branch on 2012-11-13 - both paths
(sysconfig and distutils.sysconfig based) return same results.

Stefano, please use platbase as variable - see Lib/sysconfig.py :
....
INSTALL_SCHEMES = {
'posix_prefix': {

Also I think that python experts should confirm if patch is correct.
