[Featureserver] OGR layers

[Matthew Perry]

On to the next featureserver adventure; getting an OGR layer set up as
a data source.

I have a recent gdal/ogr svn installed with the ngpython bindings and
I can confirm that they're working well.

I've set up the cfg file like so:
[sbroads]
type=OGR
dsn=/home/perry/data/sbroads/sbroads_26910.shp
layer=sbroads_26910

But when I try to access the features via http, I get the following
error message:

=======================
An error occurred: 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: '/var/www/.python-eggs'

The Python egg cache directory is currently set to:

  /var/www/.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.

  File "./FeatureServer/Server.py", line 180, in cgiHandler
    service = Server.load(*cfgfiles)
  File "./FeatureServer/Server.py", line 45, in _load
    config, section, 'DataSource')
  File "./FeatureServer/Server.py", line 22, in _loadFromSection
    module = __import__("%s.%s" % (module_type, type), globals(),
locals(), type)
  File "./FeatureServer/DataSource/OGR.py", line 2, in <module>
    import ogr, osr
  File "build/bdist.linux-i686/egg/ogr.py", line 7, in <module>
  File "build/bdist.linux-i686/egg/_ogr.py", line 7, in <module>
  File "build/bdist.linux-i686/egg/_ogr.py", line 4, in __bootstrap__
  File "/usr/lib/python2.5/site-packages/pkg_resources.py", line 800,
in resource_filename
    self, resource_name
  File "/usr/lib/python2.5/site-packages/pkg_resources.py", line 1229,
in get_resource_filename
    return self._extract_resource(manager, zip_path)
  File "/usr/lib/python2.5/site-packages/pkg_resources.py", line 1250,
in _extract_resource
    self.egg_name, self._parts(zip_path)
  File "/usr/lib/python2.5/site-packages/pkg_resources.py", line 880,
in get_cache_path
    self.extraction_error()
  File "/usr/lib/python2.5/site-packages/pkg_resources.py", line 846,
in extraction_error
    raise err
=======================

I'm not sure why it's trying to install any eggs on my system since I
have all the dependencies already. Anyone have any thoughts on how to
get this working?
