Trac installation problem


I’ve used both the DreamTracInstall script and also the Natmaster instructions in an attempt to get Trac installed on our hosting. No matter what I do, I always end up with the same error when I go to our trac page:

Trac detected an internal error:

‘trac.web.auth.LoginModule’ object has no attribute ‘ignore_case’
Traceback (most recent call last):

Has anyone else come across this problem before? I’ve done some reading around the net but haven’t found this specific problem mentioned anywhere else. This leads me to think it must be something to do with my installation environment, but I don’t have enough experience of linux installs to know where to look or what to look for in terms of a solution.

Any help would be appreciated.
