Trac 설치시 PYTHON_EGG_CACHE Permission denied 오류

Trac을 10.0.4 버전 사용하다가 0.11로 다시 설치를 했는데 자꾸 저런 에러가 나네요.

분명히 httpd.conf에 PYTHON_EGG_CACHE를 /tmp로 설정했는데 인식이 되지 않나봐요..

영문을 도대체 모르겠네요.. 혹시 아시는 분 계시면 알려주시면 정말 감사하겠습니다.

아파치 Trac 설정이구요..
-----------------------------------------

SetHandler mod_python
PythonInterpreter main_interpreter
PythonHandler trac.web.modpython_frontend
PythonOption TracEnvParentDir /home/trac
PythonOption TracUriRoot /trac
SetEnv PYTHON_EGG_CACHE /tmp
PythonDebug on

이건 오류 메시지 입니다.

ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

[Errno 13] Permission denied: '/root/.python-eggs'

The Python egg cache directory is currently set to:

/root/.python-eggs

Perhaps your account does not have write access to this directory? You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.
