[Trac] WebAdmin Plugin Installation

[Rob Wilkerson]

I'm trying to install the WebAdmin plugin and I *think* I'm following
all of the instructions, but I keep getting a permissions denied error
when I try to access the project URL.

Environment:
FC 5
Apache 2.2
Subversion 1.3.2

I downloaded the egg.zip file and removed the zip extension before
placing the egg file in /path/to/my/trac/project/plugins.  The owner
of the file is apache.apache and the permissions are 500.  So the
apache user has read and executable perms to the egg itself.

I set the cache file to /path/to/my/project/tmp and, although owned by
root, the directory is rwx for everyone (777).  Still, I get:

================================================
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:
'/opt/projects/tmp/tracwebadmin-0.1.1dev_r2765-py2.4.egg-tmp'

The Python egg cache directory is currently set to:

  /opt/projects/tmp

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.
================================================

What am I missing here?  /opt/projects/tmp is not web accessible, but
I didn't seen anything that indicated that it needed to be.  If that
is the case, then how to I specify the PYTHON_EGG_CACHE value?  If
that's not the problem, then any suggestions of where to look next
would be appreciated.  I've looked at the troubleshooting suggestions
and I *think* I'm okay with all of those.

Thanks.
