missing extensions warning is unclear

[Georgi Kodinov]

I'm running bzr.dev from the source directory.
On normal operation (e.g. update of bzr.dev own repository) it started returning warnings:

$ bzr pull
Using saved parent location: http://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev/
No revisions to pull.

It's doing this on bzr version as well :

$ bzr --version

Hi Joro,

What this means is that you should run 'make' in the source directory each time you update/pull into it, to make sure the compiled extensions are built. However, the message is apparently unclear and I'll update it so that it

- has a shorter list of the failed extensions
- specifically suggests running make

It looks like Python does not i18nize its messages so we can shorten this by matching strings::

mbp@lithe% LANG=de_DE.UTF-8 python -m aotehuaoteu
/usr/bin/python: No module named aotehuaoteu

Hi Martin,

Thanks for the tip. That did it for me. I've updated my cronjob now and it's all back to normal.
