Trac EGG Permission denied 에 대해서 질문있습니다.

제가 Fedora 9 에서 Trac 0.10 버전의 Trac을 설치 하였는데요

WebAdmin, AccountManagerPlugin을 설치 하였습니다.

그런데 WebAdmin은 잘되는데, AccountManager가 안되네요

egg파일을 만들어서 easy_install로 설치 했구요

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: '/usr/lib/python2.5/site-packages/TracAccountManager-0.1.3dev_r5273-py2.5.egg-tmp'

The Python egg cache directory is currently set to:

/usr/lib/python2.5/site-packages/

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.

이런식으로 나오네요. 그래서 구글링을 좀 해서

conf 파일에 SetEnv PYTHON_EGG_CACHE /usr/lib/python2.5/site-packages/ 를 해주고 restart 해줬는데

이런 현상이 계속 나오는거 같아요 제가 뭐 놓친게 있나요?
