Hi everyone

I am new user to graphite and i don't know python.

My goal is to build CentOS rpms for graphite family. I also want to use python27 from RedHat(and now CentOS) Software collection. Using python from software collection is mandatory in my case.

Briefly: i am running graphite-web development server and once it got a request, it reports this message: ImportError: No module named defaults

The long story follows.
BACKGROUND
Software collections (SCL) is the way to have as many concurent versions of software as i want in CentOS . In my case i have standard python2.6 which is heavily used by centos packaging system and is hard to replace in production. With SCL i can use python33 or python27 for any single program i want. For example, when i build graphite-web, i am running command
scl enable python27 'python check-dependencies.py'; python binary is found via modified environment variables, and python2.7 will be default.

STORY
I built some rpms for python27 libraries which are required by carbon and graphite-web
I have python27-pithon-django for example, as well as whisper, carbon, uwsgi, twisted, etc
I was able to run carbon under python27 and it seems to work fine and accept data.
Then i faced with problems running graphite-web via uwsgi. Going deeper and deeper i aned up with a clean Centos 6.5 chrooted environment where i install my packages and building graphite-web from source.

I am using latest version available, 0.9.12.  scl enable python27 'python check-dependencies.py' said i have no fatal problems.
Then i install graphite-web with  

scl enable python27 'python setup.py install'

Here is my changes to config, i only set SECRET_KEY:
diff -u local_settings.py.example local_settings.py

Next, i am running devel server with 

scl enable python27 '/opt/graphite/bin/run-graphite-devel-server.py --port 32770 /opt/graphite'

And here is the output after one request sent

And now i have no idea where to look information on how to handle this problem.
