It seems as though when roundup is installed in a virtualenv the
roundup-demo script is unable to find the templates.

Tested on Debian testing with:

  roundup 1.5.0
  virtualenv 1.11.4

Steps to reproduce:

 # virtualenv venv
 # source venv/bin/activate
 # pip install roundup
 # roundup-demo

This seems to be caused by the templates being installed into:

  venv/share/roundup/templates/

but the 'roundup.admin' module imported by the 'roundup-script' is from:

  venv/local/lib/python2.7/site-packages/roundup/admin.py

which in turn (via AdminTool.listTemplates()) is looking for templates in:

  venv/local/lib/python2.7/site-packages/share/roundup/templates
  venv/local/lib/share/roundup/templates
  venv/local/share/roundup/templates

but the templates are located in:

  venv/share/roundup/templates

and there is no symlink for:

  venv/local/share -> venv/share


I am guessing this also will cause problems from 'roundup admin install'.

A temporary workaround for anyone experiencing this issue is to create a
new symlink after initialising the virtualenv:

  ln -s ../share venv/local/share
